Abstract
The invention relates to a device with an annular cold air low-heat-storage quick start ignition and combustion system. The device is characterized in that an ignition and combustion device is composed of a combustor body and an ignition device of which an ignition end extends into the combustor body, wherein the ignition and combustion device is arranged in a combustion air duct; the combustion air duct is connected with an air supplementing duct and an air distribution duct; the air supplementing duct is provided with an adjusting damper; a communicating chamber is provided with an expansion joint; a thermal fire-proof layer is arranged outside the device with the annular cold air low-heat-storage quick start ignition and combustion system. In an ignition starting process of a boiler, primary hot air volumes of the air supplementing duct and the air distribution duct are adjusted through the adjusting damper, so that hot air and fuel are fully mixed and combusted and the combustion efficiency is improved; the purposes of low oil consumption and quick start of a circulating fluidized bed boiler are reached by reducing the lengths of the ducts, reducing the using amount of the thermal fire-proof material and reducing the heat storage capacity of the ducts.
Description
Technical field
The present invention relates to wind ignition combustion system device of a kind of CFBB, particularly a kind of with the low quick starting ignition combustion system of the accumulation of heat device of ring cold wind.
Background technology
The CFBB generating set is to take CFBB as generation driving force.When starting CFBB, the general bed lower oil gun combined launch mode of going to bed that adopts, take under bed starting ignition as main.In order to realize ignition under bed, CFBB is provided with the wind ignition combustion system one time, and one time the wind ignition combustion system comprises burning ,Bu Feng air channel, air channel, air distribution air channel and ignition under bed burner etc.In start-up course, CFBB starts at every turn and debugs all and will consume a large amount of fuel oils; As: the startup of 200MW CFBB generating set and debugging consume fuel oil just up to 1000 tons, and while normally moving, annual fuel oil consumption reaches 100 tons of left and right; 300MW CFBB generating set Start-up and Adjustment fuel consumption is larger, and this just drops at the cost that has increased significantly enterprise.In addition, in order to improve heating rate, promote the mixed combustion of fuel oil and air, oil gun need to be equipped with suitable atomizing piece atomized fuel.CFBB start and debug process in, need to be by repeatedly adjusting atomizing piece to improve the atomizing effect of fuel oil, this just cause the CFBB startup and debug process very loaded down with trivial details; In addition, when, fuel atomization effect not high in atomizing piece atomization reliability is bad, also be easy to cause oil droplet to drop onto in the burning air channel, not only cause the fuel oil waste, also can affect CFBB and normally start.
Summary of the invention
The present invention has overcome above-mentioned defect, and purpose is reasonably to regulate by damper the air quantity of mending wind air channel and air distribution air channel, and the start-up burner fuel oil is fully burnt; By shortening air channel length, reduce the use amount of heat insulating refractory material, thereby reduce the air channel heat storage capacity, realize that CFBB hangs down oil consumption, starts fast, provide a kind of with the low quick starting ignition combustion system of the accumulation of heat device of ring cold wind.
The present invention sketches with the low quick starting ignition combustion system of the accumulation of heat device context of ring cold wind:
The present invention is with the low quick starting ignition combustion system of the accumulation of heat device of ring cold wind, it is characterized in that: start-up burner, expansion joint, communication chamber, benefit wind air channel, burning air channel, air distribution air channel, damper and thermal insulation fire-resistant layer, consist of, start-up burner is that the igniter stretched in burner body by burner body and firing tip forms; Start-up burner is arranged in the burning air channel, burning Yu Bufeng air channel, air channel and air distribution air channel are connected, be provided with damper on benefit wind air channel, be provided with expansion joint on communication chamber, the outside of hanging down the quick starting ignition combustion system of accumulation of heat device with ring cold wind is provided with the thermal insulation fire-resistant layer.
The present invention makes boiler in the ignition trigger process, regulates a hot blast rate mending wind air channel and air distribution air channel by damper, makes the mixed combustion fully of hot-air and fuel oil, improves efficiency of combustion; By shortening air channel length, reduce the use amount of heat insulating refractory material, reduce the air channel heat storage capacity, realize the purpose that CFBB hangs down oil consumption, starts fast.
The accompanying drawing explanation
Fig. 1 is with the low quick starting ignition combustion system of the accumulation of heat apparatus structure schematic diagram of ring cold wind
In figure: the 1st, start-up burner, the 2nd, expansion joint, the 3rd, communication chamber, the 4th, mend wind air channel, the 5th, burning air channel, the 6th, air distribution air channel, the 7th, damper, the 8th, thermal insulation fire-resistant layer.
The specific embodiment
The present invention is achieved in that below in conjunction with accompanying drawing and does and illustrate with the low quick starting ignition combustion system of the accumulation of heat device of ring cold wind.
See Fig. 1, the present invention is with the low quick starting ignition combustion system of the accumulation of heat device of ring cold wind, by: start-up burner 1, expansion joint 2, communication chamber 3, benefit wind air channel 4, burning air channel 5, air distribution air channel 6, damper 7 and thermal insulation fire-resistant layer 8 form, and start-up burner 1 is that the igniter stretched in burner body by burner body and firing tip forms; Start-up burner 1 is arranged in burning air channel 5, burning air channel 5 is connected with benefit wind air channel 4 and air distribution air channel 6, be provided with damper 7 on benefit wind air channel 4, in order to regulate the ratio of mending air quantity and air distribution amount, thereby fully burning of fuel oil, combustion flame fully mixed with benefit wind.Be provided with expansion joint 2 on communication chamber 3, be beneficial to the combustion apparatus bulk expansion.Outside with the low quick starting ignition combustion system of the accumulation of heat device of ring cold wind is provided with thermal insulation fire-resistant layer 8, and the air channel 5 that can prevent from burning burns out because of excess Temperature.
Boiler, in the ignition trigger process, regulates by damper 7 hot blast rate mending wind air channel 4 and air distribution air channel 6, makes the mixed combustion fully of hot-air and fuel oil, improves efficiency of combustion; By shortening air channel length, reduce the use amount of heat insulating refractory material, reduce the air channel heat storage capacity, realize eventually the purpose that CFBB hangs down oil consumption, starts fast.
