Chongyang County, Hubei Province since the second half of 2015 to carry out the work out of small coal-fired boilers, non-New 20 tons of steam / hour and below the coal-fired boilers, the full implementation of small coal-fired boilers out of work, with environmental protection, Development and Reform Commission, by letter and other related sector wages, work to strengthen the efforts to promote thorough investigation of strict control to ensure that the county's non-compliance of small coal-fired boilers have all been eliminated remediation. In the specified date (June 30, 2017) completed the small coal-fired boilers out of the task before. Up to now, Chongyang County is not a new coal-fired boilers.

It is understood that, recently, joint quality supervision department of Chongyang County People's Government of Hubei Province, a special selection of personnel to carry out "looking back" activities for the phasing out small coal-fired boilers, special personnel division of responsibilities is based on special teams, focus on examination paper, under chemicals, wine, agriculture, and several other sectors and enterprises of boiler equipment, non-small coal-fired boilers happen "resurgence" phenomenon.

Classification is the use of fuel oil-fired boiler and practical, this boiler is the boiler variety of diesel fuel and waste oil, his overall construction and arrangement of the gas boiler is similar to a common classification of mechanical and steam materialized style.

Cause of the high energy consumption of electric horizontal steam boiler hot sales through a lot of practice and testing, has made great progress in terms of a unified understanding of the design and practice getting closer and closer. Biomass boiler is a kind of boiler to biomass energy as a boiler fuel called biomass boilers, steam boilers into biomass, biomass hot water boiler, biomass stove, biomass thermal oil heaters, vertical raw biomass boilers, biomass boilers and other horizontal. There are heating and hot water boiler bath for two purposes. Hot water boiler by circulating hot water circulation pump hot water holding tank, the tank hot water heating cycle can be achieved bath object; hot water boiler by circulating hot water circulation pump heating conduit, through the heat sink (radiator) people can achieve heating requirements; hot water boiler and hot water circulating pump with heat exchanger can be achieved bathing and heating dual function. Currently, electric steam boiler heating operation and management, divided into two categories: professional management and unit housing construction sector management itself, the management level is generally low. Professional management in good condition, a few self-management units at a high level, in the most basic high energy consumption, low efficiency of state. In addition, widespread attention heating social benefits, but energy-saving consciousness, the application of new technology, new achievements of small, long-term stay on the extensive experience of management, not to the level of refinement of scientific management. For a long time, in the development plan, the electric heating steam boiler, a new, integrated planning joint planning of lack of awareness. Residential construction and use of all available space, scattered along the road of small hot water boiler room has become a matter of convenience. Form a compact electric steam boiler steam boiler and a small capacity electric power consumption is large electric steam boiler birth defects. Forming two small facts, and indeed closely related to the lack of unified planning, but also because of lack of planning and hard to avoid blindness. In the past for a long period of time, various safety considerations due to the heating of the design, the design heat load calculation results generally much larger than the actual required value. Therefore, the emergence of the world's more than a radiator, electric steam boilers, large pumps, large diameter of the situation, the mainframe carriage pull carts situation in the world, the phenomenon of low load, the flow is widespread. This is because the designers of the factors affecting the heating of insufficient knowledge, poor operations management such as heating, furnace workers low level of technology. They worry that heating is not hot enough, dare reduce the thermal load, resulting in equipment is still too large, creating a vicious cycle.

Henan gas treatment condensing boiler operation in the secondary combustion Accident Henan condensing gas boiler, deposited in the rear of the boiler flue gas condensing Henan combustibles (soot, carbon black) re-ignition combustion phenomenon called secondary combustion, also known as Henan condensing gas boiler flue tail and then burned. It will backpass severe, air preheater, induced draft fan and other equipment economizer even destroyed. 1. Henan condensing gas boiler secondary combustion phenomenon (1) a sharp rise in exhaust gas temperature, chimney to take smoke, fire or even smoke. (2) changes drastically furnace pressure, positive pressure occurs. (3) severe flue enclosure dark red. (4) when there is an air preheater, a sharp rise in the temperature of the hot air, pressure instability. (5) blast doors sometimes the tail action. Cause 2.Henan condensing gas boiler secondary combustion (1) poor atomization burner, oil, gas and incomplete combustion into the rear of the boiler. (2) combustion improperly adjusted, with insufficient wind or with the wind unreasonable. (3) Henan condensing gas boiler startup, shutdown during low furnace temperature, the unburned fuel in the furnace. (4) When shutdown or boiler fire, air gun valve is not closed. (5) the combustion chamber negative pressure is too large, too late to make the gas burn it into the rear of the boiler. (6) Long-term non-stop cleaning backpass furnace, accumulating a certain amount of soot or carbon black. (7) through the air preheater flue or leakage. 3. The gas processing condensed Henan secondary combustion boiler (1) should immediately stop the gas, stop the wind, shutdown. (2) closing the flue, and a baffle duct around the door opening, is prohibited to start sending, induced draft fan. (3) immediately extinguishing device into steam, carbon dioxide or other fire extinguishing means, (4) Strengthening Henan condensing gas boiler feed water and turn on the water, open the valve or economizer recirculation tube to protect the economizer is not burning. (5) When the exhaust gas temperature close to the temperature of the injected steam, or less than 150 deg.] C over 1h and stable openable inspection hole inspection, after checking element determines an ignition source, before the fan starts ventilation and cooling. (6) when the temperature drops below the flue 50 ℃, check before entering the flue tail heating surface, and should completely remove the flue soot. If not burning, can be re-started ignition; if burning, should be replaced, repaired burning member.
