Steam bath pressure water tube boiler dealer is too many forms, take an ordinary fast-packed 4-ton steam boiler. Water is heated into steam in the drum and heat is emitted by fire in the furnace, which is the principle of the steam boiler. Say the boiler first the pot. The boiler is a drum boiler with water cooling. Two return pyrotechnic tubes are arranged in the left and right parts of the drum, and the front cigarette box in the front part of the drum is turned back. Between the drum and the bottom box, there is a drop tube and a water-cooled tube, forming the frame of the combustion chamber. There is a steam separator on the top of the drum to reduce the water produced by steam. The heating surface of the boiler is the lower part of the drum, water-cooled pipe and pyrotechnic pipe. The combustion part consists of a chain grate and a drive device, Add the boiler frame on the grate of the composition of the combustion chamber composition. Surrounded by refractories. Coal from coal hopper, there are coal gate to control the thickness of coal seam while sealing the front of the air. The lower part of the combustion chamber is the place where the blast enters, and this kind of boiler has great resistance and needs forced blast. Cinder, discharged from the back of the grate through hawk iron and sent out of the furnace by the slag extractor. From the back of the boiler, the flue gas goes forward from the first return pipe of the boiler, the second return pipe returns to the rear part of the boiler, and then goes into the dust collector to separate the ash, and then through the draught fan, it is discharged from the chimney. The induced draft fan is not only the exhaust gas, but also necessary for the negative pressure operation of the boiler. Steam boiler is pressure capacity Device, safety device is necessary. Essential water level gauges, pressure gauges, safety valves, thermometers, electric pumps that can replenish water under pressure, and steam pumps that can also be used in the event of power outages. Boiler water must be softened and water treatment equipment.

Since "strong piece autumn and winter air pollution in a comprehensive way, determined to win the Battle of Hebei blue sky" press conference was informed, Hebei Province, to make arrangements for winning the Battle of the blue sky, requested the preparation of implementation of the blue Battle Hebei Province Government Information Office held three-year operational plan and cleaning winter heating three-year plan to ensure that changes every year, three years, a large bear fruit.

Really good job of air pollution prevention and control work in the past year, Hebei Province, adhere to the scientific governance haze, collaborative governance haze, haze iron-fisted rule, will coordinate development of pressure energy, reduce coal, running enterprises, dust, vehicle control, by Green et key tasks, play a set of tackling the problem, the main root of the problem "combination punches." Where the complete substitution of gas for coal, electricity-generation coal transformation 2,537,000, Yajian steel production capacity of 27.54 million tons, 21.32 million tons of iron, coke 8.088 million tons, 10.68 million tons of coal, Reconstructing "scattered dirt" Enterprise 38785, off stop banned enterprises 68747, the new afforestation area of ​​741 hectares. At the same time, also launched a special inspection of law enforcement inspectors and four comprehensive management of air pollution, to carry out unannounced visits to check the dark, spot checks, cross-law enforcement, road law enforcement to crack down on environmental violations, and earnestly solve the "last kilometer" problem.

Director, Office of Atmospheric Hebei Province, the provincial Environmental Protection Bureau Director Gao Jianmin, said: "This year we will develop science of air pollution control 3-year operational plan, a clear timetable, route map, to promote the key cities 'insurance bottom line, back ten' focus on tackling to ensure that air quality 'changes every year, three large effective', and strive to Shijiazhuang, Hengshui, Tangshan City, the first exit after ten. we will actually improve air quality and enhance, to better respond to the concerns of the masses, improve people's livelihood well-being, and enhance people's sense of well-being obtained.

How to prevent gas hot water bath pressure water tube boiler dealer explosion gas hot water boiler belongs to the category of special equipment, thermal equipment and is a frequently in high pressure high temperature state, it is inevitable some small problems that may occur during operation, this is normal; but if not in place or because of negligence, they are likely to make the boiler exploded. So, for safety equipment and personal safety, we have to understand some common sense prevention hot water boiler explosion. 1, hot water boiler furnace explosion prevention occurs first on the boiler design, should be strictly thermodynamic calculation and strength calculation in accordance with the requirements of GB50041-1992 "boiler room design specifications", the structural arrangement should be reasonable, material quality should meet the requirements. Boiler manufacturing, construction plans should ensure compliance with national quality boiler scale delineation. Boiler safety accessories should be complete, agile and reliable, and maintenance schedule, often check on the failure of the attachment timely replacement. Schedule for maintenance of the boiler, the outer part of the boiler maintenance, subject to the existence of timely repairs and reconstruction to ensure test quality standards. 2, prevention of fuel, gas hot water boiler furnace explosion at the point of blast furnace to double-check each gas line, oil line is tight (leak), pressure is normal, Installation and reconstruction of new oil and gas pipelines necessary to purge and clean. Check the ignition lead before the drum whether the fan has to take the air 5 ~ 10min, after ignition failure to analyze the reasons, and then restart the ignition process to take the air ignition. Boiler use permit and inspection certificate did not apply for the boiler, furnace stokers right to refuse point. Enterprises should choose a fireman permit manipulation of experienced fireman point-furnace work, fireman staff should strengthen the inspection tour, identify problems in time to prevent the flame; flame once found, should immediately cut off fuel. Boiler installation should be controlled protection device, comprising an automatic ignition, flame protection, automatic adjustment of combustion and the necessary alarm chain protection.

Hot water bath pressure water tube boiler dealer water filling boiler considerations and parameters between boiler pressure hot water boiler of this kind in which the boiler is a common and frequently used species, but also in terms of all of us, need to have a comprehensive knowledge and understanding, because the only way to be correct and rational use of hot water boilers and have good results, but also to avoid misuse and adverse impact. 1. boiler parameters, whether on the same hot water boiler and steam boiler? From a professional point of view, the parameters of hot water boilers and steam boilers are not exactly the same, there are some differences, because the parameters of the boiler steam boiler steam boiler is concerned is the number of generated operating pressure and temperature steam, hot water thermal power boiler in terms refers to the boiler, the water supply and return water pressure and temperature. In addition, its different parameters, it corresponds to the unit is not the same. 2. Boiler Feed water pressure Cautions Boiler Feed pressure hot water process, there are some considerations, which is specifically as follows: (1) Sheung boiler heating system should be carried out separately, can not be together, because the boiler when you stop running between the boiler and the system is cut off. At the operational level, is you want to Sheung Shui to low water boiler expansion tank, then the system can Sheung Shui. Water Supply System, which can be used to perform Sheung pressure of the water filling the water system, if the pressure is less than water, circulating pumps can be used for water filling system. (2) If the system is filled with water by the circulation pump, which is specific to the operation: the boiler return pipe inlet valve is closed and the circulating pump will be multiplexed into the water pressure in the system until the system after the completion of charging water, then adjust the water level in the boiler. Meanwhile, while the system is filled with water, to be noted that the exhaust gas system. 3.1.4MV electric heating hot water boiler, heating area which is how much? 1.4MV electrically heated hot water boiler, its heating area is calculated, it needs to know the required heating power per square meter, heating, boiler pipes and boiler efficiency loss of these parameters, in order to obtain specific numerical values. If the heat required for heating power per square meter is 80W / h, boiler conduit 20% loss, then, the electrically heated hot water boiler heating area of ​​10,000 m2. However, this is the theoretical value, there may be some discrepancies with the actual value, without taking into account other external factors in this case.
