szs oil and gas hot water boiler for pharmaceutical industry

Recently, Taiyuan, Shanxi Province Environmental Protection Leading Group issued a circular on promoting the transformation of ultra-low emissions and low nitrogen transformation of biomass boilers gas-fired boiler. Resolutely implement - the latest requirements "2018 in Beijing, Tianjin and the surrounding areas in 2019 autumn and winter tackling air pollution comprehensive management action plan" in, and further reduces boiler emissions standards.

Located in urban construction area of ​​biomass boilers to complete the transformation of ultra-low emissions at all before 31 October 2019. After the transformation to achieve ultra-low emissions coal-fired power plants. 6% of the oxygen content of the reference, soot, sulfur dioxide, nitrogen oxides emission concentration of not more than 10,35,50 mg / m. Rear of the boiler can be installed efficient dust removal, desulfurization apparatus or stock updates Ultra Low NOx emissions (nitrogen oxides emission concentration is not higher than 30 mg / m3) gas boiler or an electric boiler.

December 31, 2015 installation of ultra-low nitrogen gas boiler to complete the transformation of the October 31, 2019, after the installation of gas boilers used to complete the transformation of the ultra-low nitrogen October 31, 2020. After transformation of nitrogen oxide emissions concentration up to 30 mg / m. District heating gas boiler discourage updated low nitrogen burners, home improvement flue gas recirculation device to transform the way, is updated to encourage direct ultra-low nitrogen emissions boiler.

Pressure fuel boilers interpretation of the overall daily operation and maintenance of oil-fired boilers with atmospheric corrosion knowledge structure, including boiler and auxiliary equipment of two parts. Boiler furnace, drum, burner, water wall superheater, economizer, air preheater, and the furnace wall, etc. The main frame member constituting the core part of the steam production, called boiler. Boiler body is in two main parts and drum furnace. Also known as the furnace combustion chamber, fuel combustion for space. The solid fuel on to the grate, referred to as a fire bed combustion furnace Stoker, also known as fire bed furnace; solid fuel furnace liquid, gas or pulverized, is injected into the combustion chamber is called the fire chamber burner, also known as the furnace fire chamber; air coal particles burn hold it was boiling, and the furnace is inferior fuel suitable for combustion is called fluidized bed furnace, also called fluidized bed furnace; coal particles so that an air flow rotated at high speed, and strongly called fire cylindrical cyclone furnace hearth. Boiler pressure fuel daily operation and maintenance link and chemical corrosion, turbine attendant prepare enough desalinated water, oxygen, water passing temperature no higher than the drum wall temperature 50 ℃; Sheung during hot drum wall temperature should be after the temperature of the metal is not more than 40 ℃ before a new installation or repair departments boiler Feed records an indication of expansion. Sheung summer time less than 2 hours, at least 4 hours in winter, when the temperature and Sheung drum wall temperature difference of less than 40 how ℃ boiler reheater corrosion protection? after turbine fight gate, boiler guarantee a blower, an induced draft fan is running the best cross retain two oil gun. turn reheaters to the empty exhaust steam reheater hydrophobic doors and air doors corrosion, anti-corrosion of the reheater steam temperature is lower than a predetermined deg.] C for 400 control drum water level within an allowable range. anticorrosive time less than 20 minutes after stopping two oil gun operation. guarantee furnace pressure when 50--100Pa, each of the flaps open, baffle for ventilation less than 5 minutes, stop sending, fan, each of the flaps closed tailgate may be appropriate to accelerate Sheung speed.

Concern three gas szs oil and hot water boiler for pharmaceutical industry part of the gas hot water boiler is now in the streets everywhere are commonly used appliances, was warmly praised countless families. Since the advent of the diversification of gas hot water boilers, domestic hot water use headache solved the problem came to a great extent alleviate the difficulty of water, hot water is more difficult dilemma. Gas hot water boiler and hot water is able to provide us with such caring and thoughtful mainly due to the following three components. First, the ignition system. Gas hot water boiler function in that the ignition system ignites a mixture of air and fuel, its main components are: the ignition transformer, the ignition electrode, a high voltage electrical cable fire. A more secure electronic ignition system called ignition pulse, is widely used in many energy-saving gas boiler manufacturers. Because the time-saving convenience, simply by pressing a finger on it, and is safe, accidents do not occur by accident flameout occurs, once the stall condition occurs, the control system can close the solenoid valve, turn off the gas path. Second, the fuel system. Function boiler fuel gas water system is required to ensure that the fuel burner. The fuel oil burner system are: tubing and fittings, pumps, solenoid valves, nozzles, heavy oil preheater. The main burner gas hot water boiler with a filter, pressure regulator, a solenoid valve, and then firing solenoid valve, the fuel valve. Third, the electronic control system. Gas hot water boiler is the electronic control system command center and contact center system of the above, the main control element is a control box, for different burner with a different programmer, the programmer has common: LFL series, LAL series, LOA series, LGB series, the main difference is the time of each different program steps. The above is an important part of three gas hot water boiler. Gas hot water boiler manufacturer which is good when the next issue each family at the time of purchase will encounter, in fact, for this issue after reading this article may be an integral part of consumers based on the above three gas hot water boiler quality of the merits to determine whether it qualified as a selection criteria.

Boiler fire phenomenon, how to do 1, furnace pressure fluctuations or to limit and alarm. 2, no flame detector flame, flame flameless television display. 3, flue gas oxygen abnormal fluctuations. 4, steam pressure steam temperature dropped drastically. 5, furnace black, black smoke chimney. 6, the flue gas temperature is reduced. 7, MFT action, turbine trip, splitting the unit. Cause 1, the furnace combustion conditions organizations unreasonable, improper wind coal proportion. 2, the load is too low, unstable combustion conditions without oil combustion vote, or vote, although oil but not good combustion results. 3, cast oil, poor quality oil, oil spray gun is bad, low oil pressure, oil system failure. 4, poor coal quality, coal is too rough, the water is too large pulverized coal combustion adjustment is not timely. 5, the primary air temperature, air pressure is too low. 6, boiler MFT protection action. 7, a large area of ​​the furnace coke collapse, smashing off the flame. 8, severe water wall pipe explosion will blow out the flame. 9, all coal-fired condition, mill pulverizing system failure caused most or all trips. 10, a part of auxiliary machinery such as a fan, blower, fan, air preheater tripped, causing unstable furnace combustion conditions. 11, sootblowing properly, resulting in a large number of normal operation of the furnace ash effects of fire inspection of the boiler. 12, bottom seal damage. Treatment 1, the boiler fire, MFT should be action, otherwise manual MFT. 2, normal inspection device linkage linkage MFT, confirm that all fuel cut. 3. quickly identify the cause, try to eliminate the boiler can be re-ignition, the recovery unit operation. 4, when the mill started again after the trip, the trip must be the primary air tube mill full purge. 5, the MFT operation, checks, Fan normal operation, automatic furnace vent. 6, the MFT movement, check all the secondary purge air damper position is set, the total air volume is automatically adjusted to 30 ~ 40% BMCR sufficiently purged air volume. 7, the MFT operation, when the turbine is in a state disk drive, the disk drive must continue until the normal turbine eccentricity, before re turn red. 8, if temporarily unable to identify or eliminate the cause, restart and could threaten personal safety equipment, non-start. 9, processing according to the corresponding predetermined remaining MFT.
