waste cooking oil fired steam boiler

Dezhou City, Shandong Province issued - an important part of "Dezhou 2018 2020 coal consumption reduction alternative work" (the "Program"), the Yajian coal consumption as an ecological civilization construction and environmental protection work, and resolutely fight pollution prevention tough fight. "Plan" put forward, as of 2020, total coal consumption Dezhou control in less than 18.5 million tons, clean heating rate of 70%.

According to "program" requirements, Dezhou vigorously for shutting down the environmental, energy, security and other 300,000 kilowatts of coal-fired units of non-compliance, especially running at least 20 years of pure condensing units and over 25 years of condensate pumping thermoelectric unit. At the same time shutting down out of small coal-fired boilers to reduce coal pollution. Upon completion of the city's 10 steam tons / hour and coal-fired boilers are all clear on the key areas in national, provincial and determined basically eliminated 35 tons of steam / h coal-fired boilers, 65 tons of steam / hour or more coal-fired boilers completed energy efficiency and ultra-low emissions transformation.

Dezhou will also expand the scope of central heating, promoting clean urban and heating, 2020, the Center City District (Germany City, Texas Economic Development Zone, the Canal Economic Development Zone) central heating area of ​​45 million square meters, the other 10 counties (cities, districts) central heating area of ​​41 million square meters, the implementation of central heating pilot projects in rural areas where conditions permit. For areas not covered by central heating, according to the resources in the area of ​​heating conditions, combined with infrastructure construction, promote the substitution of gas for coal to other electricity-generation clean energy alternatives such as coal and biomass. As of 2020, Dezhou city's average clean heating rate of 70%. Among them, the city basically clean heating comprehensive coverage, average clean heating in rural areas reached about 55%.

In addition, Dezhou will continue to increase the proportion of natural gas consumption, substitution of coal consumption, encourage the development of direct supply of natural gas to large users to promote key industrial enterprises, industrial parks to achieve direct supply of natural gas. By 2020, increase the proportion of natural gas consumption in energy consumption to about 7%.

Types of High Pressure Boilers

A boiler is a vessel in which water is heated under pressure and vaporized into steam for a specific purpose. There are several different kinds of boilers, heated by coal, solid fuel, oil or gas, also have high pressure steam boiler and high pressure hot water boiler. Boilers vary widely in size from small, portable or shop-assembled units to large furnaces that burn 6 tons of coal a minute. Boilers operate at positive pressure, and all parts must be strong enough to withstand the pressure of the steam they generate. Most high-pressure boilers are used for commercial or industrial purposes.

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.
