Coal-fired boilers, fuel shots are fired, coal in the combustion chamber after the combustion heat release, the heating medium water or other organic heat (e.g., heat transfer oil, etc.) heated to a temperature (or pressure) of the thermal power plant. Coal is our energy use accounted for first, with a mature mining, transportation and sales channels, and the price is relatively low; but it also has many defects, low efficiency, resource utilization imbalance, burning emit large amounts of carbon dioxide and other harmful gases and dust, the larger impact on the environment pollution and high environmental costs.

Beijing SL Pharmaceutical Co., Ltd. as China's key high-tech enterprises, has great influence in the pharmaceutical industry. In early 2017, two-Heron relevant person in charge to get in touch fast boiler, double-Heron Pharmaceutical according to demand, our company to provide a 1-ton split steam condensing steam boiler, and is responsible for subsequent transportation, installation and commissioning work .

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.

Henan gas boiler surroundings in claim (1) prohibition of the various stacked Henan combustible gas in the boiler room, not allowed to bake anything Henan gas boiler and steam pipes. Cotton wipe oil equipment, oil rag to a safe place. (2) prohibit incineration in Henan gas boiler waste paper, waste wood, linoleum and other waste, to avoid causing a chimney fire fly, ignite surrounding combustibles. Around (3) Henan gas boiler can not be an ignition source is not close to the other heating boiler pipeline equipment. In addition, we must pay particular attention: Once Henan gas boiler appears dry (red-hot), turn off the power immediately, open all exports, remove the burner. Prohibited immediately cold water into the furnace body should wait until the natural cooling. In order to avoid or reduce the casualties caused by the explosion of a gas boiler and its social, economic losses, we can adopt a more efficient boiler explosion-proof alarm system. For example, possible to detect the concentration of combustible gas leak sensors and alarms. Domestic and now have been developed using a gas sensor, a gas leak can be utilized, for measuring combustible concentration to alert the boiler furnace. The alarm high sensitivity, fast response time made of semiconductor material, the combustible gas sensor feel gas leak alarm immediately. Water spray system can be used as preventive measures early boiler fire and explosion. With the development of technology, artificial intelligence, and more high-tech will be applied to prevent an explosion in Henan gas boiler in the past.
