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.
Oil-fired boiler combustion control and automation and whether the fuel tank on the role of specific types of boiler, this article will be introduced below, for this kind of boiler oil-fired boiler, but for now, this kind of boiler is widely application, is a common and popular types of boilers, so based on these two points, it should be taken seriously and work to learn the product, good to have a good use of effects through proper use. Notes 1. What are oil-fired boilers? This oil-fired boiler A boiler, through which the oil is atomized fuel oil burners, and then mixed with air, in suspension a combustion apparatus for combustion in the furnace. Larger capacity fuel boilers, mostly use heavy, but the larger the viscosity of heavy oil must be preheated before combustion; if the capacity is small, is the use of light oil, no need for preheat. In addition, oil-fired boilers for industrial use, mostly fueled with the use of light diesel oil. 2. whether the oil-fired boiler combustion and control system can be automated? The issue from a professional point of view, the answer is you can, that is, oil-fired boiler burning automation and control systems can be used. In addition, this kind of boiler fuel needs to be injected into the boiler furnace combustion chamber and the use of fire, there is no need to use grates facilities. Fuel oil-fired boiler does not produce ash after combustion, therefore, do not need to slagging facilities. 3. Does the oil-fired boiler have different classification criteria? It corresponds to the specific types of what? This kind of boiler oil-fired boiler, which is a different classification criteria, and correspond to different species at different classification criteria. If the fuel according to the type can be divided into two heavy gas oil boilers and boiler, light oil and kerosene are those diesel, heavy oil refers to crude oil after extraction remaining heavy gasoline or diesel oil. If use according to points, can be divided into a fuel oil-fired boiler water boilers, hot water boiler fuel, heating fuel boiler, oil bath boilers and 40 tph fired steam boiler fuel these. 4. whether the oil-fired boiler can be automatic oil burner? Why have their fuel tanks? On oil-fired boilers, can be automated using the oil burner, the ignition from the normal combustion, the air supply from the oil supply to the flame detector, and so can be automatic protection automatically, without manual operation. And this kind of boiler installed on the tank, one can play a role in filtering sediment, and second, to solve this problem come from oil-absorbing far away.
Before coming heating season, Pinggu and Yanqing, Miyun three areas have been completed six large coal-fired boiler clean energy transformation, involving a total of 1660 tons of steam, residential heating area of about 900 square meters, in order to promote the city's urban focus heating basically clean heating to make a strong contribution.
It is reported that, in addition to this rural area south of the coal-fired boiler house for reasons of space, and the remaining five of the original coal-fired boiler room facility will be retained as an emergency backup. Pinggu District-Valley heating plant boiler clean energy transformation project has been debugging equipment, the boiler room of the original four coal-fired boilers, a total of 400 tons of steam, heating an area of about 2.5 million square meters, the new 3 sets of 100 tons of steam gas boiler is equipped with a heat pump.
Also, according to plan, City Management Committee led the development of the annual Yajian coal and clean energy facilities construction program to focus on the northern region, enhance power supply, gas supply capacity, promote Plains natural gas pipeline "town pass" to protect coal demand for clean energy. The basic realization of the city's plains village "No Coal", the phasing out of bulk coal sales within the region transformation of the industry and commerce department for bulk coal sales cancellation of registration in accordance with law, in principle, be issued a new business license. For failure to implement clean heating in winter 2018 and not included in the annual village "coal to clean energy" program, full implementation of quality coal instead.
Reduction of carbon dioxide, sulfur dioxide emissions
Pinggu District Management Committee, according to the person in charge, Riverside, Xia Xing Coal Valley and heating plant is heating an area of 7.416 million square meters, of which the heating plant heating Riverfront area of 4.1 million square meters, the Xingu heating plant heating an area of 2.808 million square meters, summer Coal heating plant heating area 508,000 square meters.
By upgrading "coal to gas", three heating plants meet emission standards Beijing local standard NOx emissions of less than 30 mg / standard cubic meter, while the amount of coal Yajian 160,000 tons per year, greatly reduce emissions of carbon dioxide, sulfur dioxide, nitrogen oxide.
Among them, Xingu heating plant "coal to gas" project officially started on May 16 this year, October 20, Sheung Shui, October 27 with the ignition conditions.
Riverside heating plant "coal to gas" on May 16 this year started, has completed the boiler and associated piping, heat pumps and ancillary equipment installation, ongoing electrical, control system debugging, October 22 has been Sheung Shui, October 29 have ignition conditions.
Summer Coal heating plant "coal gas" this year officially started on August 18, has completed commissioning of boiler facilities and associated piping, heat pumps and ancillary equipment installation, ongoing electrical, control systems, etc., on October 29 water, with firing conditions.
