January first, Henan Province issued "the transformation of traditional coal chemical industry development action plan" (the "Program"), to promote the province's pollution prevention campaign of three-year action plan to speed up the traditional coal chemical industry (ammonia, methanol) industry to green transformation, to achieve high-quality development.

First, strictly control new capacity

Adherence to the red line capacity, traditional coal chemical enterprises prohibit new construction, new capacity expansion projects alone, is strictly prohibited without permission around the building does not meet the requirements of the industrial layout plan of coal chemical project in principle. The province's coal chemical projects and intensive clean-up, but according to the specified time limit has been approved to start construction of the project in principle, to construction, relocation and renovation projects must be upgraded into the base or campus planning. By 2020, the chemical industry out of the fixed bed coal gasifier intermittent exit single set of devices 300,000 tons / year of synthetic ammonia production capacity. Strict safety, fire safety, environmental protection, energy saving, water administrative licensing, implementation of the project safety, environmental protection facilities "three simultaneous" (designed, constructed and put into use) system, and resolutely shut down energy consumption, environmental protection, safety, quality, technical non-compliance enterprise. Strict implementation of the regional total energy consumption, pollutant emissions control requirements, upgrading of coal coal project be implemented reduction or equivalent alternative.

Second, increase the relocation and reconstruction efforts

Further promote the densely populated towns of dangerous chemicals production enterprises and urban built-up areas heavily polluting industrial relocation of enterprises, the implementation of an intensive investigation, the establishment of management accounting, according to "a business a policy" during mode classification advance. Priority to promoting the urban area of ​​coal chemical industry relocation, conversion or quit, not in the urban area but not in the business park to gradually move the park, according to the specified execution be discontinued or phased out. Close to exit the business enterprise to achieve the "two off three clear" (cut industrial water, electricity, removal of raw materials, products, production equipment), select the transformation of the enterprise to implement the upgrading of the standard industry benchmark, to off-site relocation According to large-scale, modern principles move into the province for involving chemical industry gathering area. Relocation upgrading of enterprises, projects and equipment should be encouraged to reach equipment industry access standards and conditions specified in the Guiding Catalog of Industrial Structure Adjustment, the use of large-scale continuous pressurized gasification plant, ammonia production capacity to 300,000 tons / year and above, coal methanol production capacity reached 100 million tons / year and above, the main push large-scale equipment.

Third, the implementation of green transformation

Before the end of 2019, coal chemical enterprises fully completed VOCs governance. And comprehensively promote the chemical industry equipment static and dynamic sealing points, storage, handling, waste water systems, unorganized process emissions and non-normal operating conditions and other root causes of remediation. As requested, the timely completion of the coal chemical industry waste discharge permit issued by the work, companies must comply with the behavior of the sewage discharge permit clear conditions, various types of environmental inspection found violations, strictly and severely investigated and dealt with as soon as possible in place. Based on "clean production audit approach", the implementation of coal chemical enterprises compulsory clean production audit coverage. Required to implement risk control measures to close the relocation of enterprises left over land.

Gas-fired energy saving price 8t coal steam boiler kuwait principle gas steam boiler with natural gas, liquefied petroleum gas, fuel gas such as city gas as fuel, the combustion in the furnace heat put out by heating the pot water, and which is vaporized into steam energy conversion device. Water pan (drum) is continuously released from the combustion of a gaseous fuel energy to heat the furnace, raising the temperature and generating steam under pressure, since the boiling point of water with elevated pressure is raised, the pot is sealed, the water vapor inside the expansion pressure is generated is limited thermodynamic form (strictly speaking, water vapor in the boiler water is heated to a constant-pressure steam drum regasified saturated formed) is widely used as an energy source. Boiler and boiler shell consists of two main furnace and ensure accessories, ancillary equipment instrumentation, control and protection system safe and economic operation of its continuous constituted. This boiler is a boiler drum with a water cooling wall at about the subregional arrangements drum pyrotechnic two return pipe, before the folded portion of the drum front smoke box. Between the drum and the tank in connection with the downcomer tubes and water-cooled bi, constituting the frame of the combustion chamber. There upper steam separator drum to reduce the water vapor out of the tape. Pan heating surface of a lower portion of the drum, and the water cooling pipe bi pyrotechnic tube. The basic components of a steam boiler and a steam boiler operating principle is constituted by a series of devices can be roughly divided into two main parts and auxiliary equipment. The main components of the boiler are: 1. Furnace: fuel burn-up and ensures that the boiler outlet gas temperature to a value of convection heating surface cooled safe work; 2, economizer: utilizing the heat of the flue boiler feedwater heating, to reduce the exhaust gas temperature, fuel economy and functions. 3, the drum: the respective heating surface and joined together and the boiler water wall tubes and other components decreased water circulation circuit. Soda storage drum, can adapt to changes in load, with internal steam separator means to ensure the quality of soft drinks, no DC boiler drum. 4, water wall: mainly radiation heating surface of the boiler, the absorption of radiant heat furnace heated working fluid to protect the furnace wall and the like. 5, combustion equipment: the fuel and air required for combustion of the fuel into the furnace ignition and stable good combustion; 6, air preheater: heating the fuel with air, in order to enhance ignition and combustion; flue gas waste heat absorption, reduced exhaust tobacco temperature, increase boiler efficiency. 7, the furnace walls: a housing to protect the boiler, since sealing and insulation. Heavy furnace wall of the small boiler may also function as a support member boiler. 8, the frame: a support member and the fixing boilers, Purple east 15:33:06 boiler auxiliary equipment are: 1, the wind equipment: induced draft fan and chimney via the flue gas generated in boiler operation sent to the atmosphere. 2, dust removal equipment: removing fly ash in the boiler flue gas. 3, the fuel supply equipment: fuel storage and transportation functions. 4, water supply equipment: water pump water supply through the water into the boiler by the processing device to. 5. Dust Cleaner equipment: removing ash from the boiler and carried away. 6, the blower device: by the air blower after exports the furnace air preheater and a coal grinding device heating applications. 7, the automatic control device: automatic detection, process control, automatic protection and automatic adjustment. IMPORTANT boiler maintenance and a maintenance, water maintenance method 1. The boiler must be a qualified treatment, which is to extend the life of the boiler, ensure the safe operation of the gas and steam. 2. The water temperature should be close to the furnace temperature, preferably above 20 ℃. 3. The need for low-water cutoff periodically inspect maintenance and cleaning. Water Level Controller cleaned at least once a month, rinse water table at least once a day. Rinse water table should be at the highest level; after flushing the water level should not be less than the minimum safe level, not as a net wash, can wash many times, but it must be flushed at the highest level. 4. require periodic blowdown operation, daily (per shift) at least once, after the sewage drain valve should be checked whether the influence by dirt and leaks; if it must be excluded. 5. Shutdown the steam pressure is not maintained, the boiler will produce steam space negative pressure air entrapment, and therefore should rise again to the fire burning total steam valve is opened. 6. smoke tube fouling will lead to increased exhaust gas temperature, so that boiler efficiency is lowered, so that the fuel consumption increases, it should periodically open the front door, brushing or blow smoke tube fouling.

Boiler startup startup boiler combustion adjustment method should pay attention to the flame monitoring, combustion and make adjustments as follows: (1) correct the ignition. Adequate ventilation furnace before ignition, the ignition first investment ignition device (or torch), then turn the gun. (2) diagonally administered fire mouth, pay attention to timely switch, the flash point was observed nozzle suitable fire, flame sought uniformly distributed in the furnace. (3) to adjust the lead note, air volume, furnace pressure should not be too large. (4) in particular to monitor exhaust gas temperature when combustion instability, the occurrence of the back pass to prevent the secondary combustion. (5) to maximize the temperature of primary air, secondary air is fed reasonable depending on the fuel. Adjusting the temperature difference between both sides of the cigarette. Do pulverizing system-OFF stable (6) operation. Stoker coal under stable powder machine speed and stability. Coal with wind stability and oxygen stable. Steam temperature, steam pressure increase stability and load stability liter.

Problematic fired boiler (1) Henan small boiler gas boiler should be noted, by the Henan coal into gas boiler, i.e. the original becomes a negative pressure is now slightly positive pressure combustion burner, the furnace must be noted that the structure and the sealing wall problem; (2) prevent explosion of the furnace, a gas fired boiler furnace to Henan, when defective or incomplete combustion of fuel atomization gas in the furnace or heating surface of the end aggregate, fire or explosion occurs, and therefore, in appropriate sites shall boiler explosion vent means, while the control program should be added to the ignition and flame protection device of automatic control, to ensure safe operation of the boiler; (3) the selection and arrangement of the burner close to the furnace in the form of, should the flame in the furnace better fullness without forming dead air; adjacent flame of the burner to avoid mutual interference; low load flame holding in the furnace central position, offset from the center of the furnace to avoid the flame center of symmetry; unburned gas-air mixture is not in contact with the heated surface , to avoid the formation of incomplete combustion gases; hot flame to avoid high-speed heating surface erosion, in order to avoid excessive heating surface so that the wall strength of overheating. Burner arrangement also consider the gas pipe and duct arrangement, easy to operate, inspection and maintenance; (4) Mechanized layered coal-fired boiler, gas boiler to change Henan, first removing its longitudinal arch, taking into account the increase in the bottom heating surface to replace the grate, grate to prevent overheating burn; (5) gas velocity Henan convection heating surface is not limited by the gas boiler ash abrasion conditions, gas velocity can be increased properly, so the convection heat transfer heating surface coefficient increases, without increasing the heating surface of the boiler, can increase the pressure of the boiler, steam-water separation capability should be noted that at this time means the pot to ensure the quality of steam, hot air for the boiler had particularly important.
