Abstract
The utility model relates to a quick starting low-heat-storage ring-cooling-air ignition burning system device. The device is characterized in that an ignition burner consists of a burner body and an ignition device, wherein the ignition end of the ignition device extends into the burner body; the ignition burner is arranged in a burning air duct which is connected with an air supplementing air duct and an air distribution air duct; an adjusting air door is arranged on the air supplementing air duct; an expansion joint is arranged on a communicating chamber; a heat-preservation refractory layer is arranged outside the quick starting low-heat-storage ring-cooling-air ignition burning system device. According to the quick starting low-heat-storage ring-cooling-air ignition burning system device, primary hot air volumes of the air supplementing air duct and the air distribution air duct are adjusted through the adjusting air door to completely mix hot air with fuel oil for burning in an ignition starting process of a boiler, so that the burning efficiency is improved; the air ducts are shortened, the using amount of a heat-preservation refractory material is reduced, and the heat storage capability of the air ducts is reduced, so that the aims of low oil consumption and quick starting of a circulating fluidized bed boiler are fulfilled.
Description
Technical field
The utility model relates to wind ignition combustion system device of a kind of CFBB, particularly a kind of with the quick starting ignition combustion system of the ring low accumulation of heat of cold wind device.
Background technology
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 wind ignition combustion system one time, and one time 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 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, be also easy to cause oil droplet to drop onto in burning air channel, not only cause fuel oil waste, also can affect CFBB and normally start.
Summary of the invention
The utility model has overcome above-mentioned defect, and object is reasonably to regulate by damper the air quantity of mending wind air channel and air distribution air channel, and start-up burner fuel oil is fully burnt; By shortening air channel length, reduce the use amount of heat insulating refractory material, thereby reduce air channel heat storage capacity, realize the low oil consumption of CFBB, start fast, provide a kind of with the quick starting ignition combustion system of the ring low accumulation of heat of cold wind device.
The utility model is sketched with the quick starting ignition combustion system of the ring low accumulation of heat of cold wind device context:
The utility model is with the quick starting ignition combustion system of the ring low accumulation of heat of cold wind device, 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 being stretched in burner body by burner body and firing tip forms; Start-up burner is arranged in burning air channel, burning Yu Bufeng air channel, air channel and air distribution air channel are connected, on benefit wind air channel, be provided with damper, in communication chamber, be provided with expansion joint, with the outside of encircling the quick starting ignition combustion system of the low accumulation of heat of cold wind device, be provided with thermal insulation fire-resistant layer.
The utility model makes boiler in 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 air channel heat storage capacity, the object that realize the low oil consumption of CFBB, starts fast.
Accompanying drawing explanation
Fig. 1 is with the quick starting ignition combustion system of the ring low accumulation of heat of cold wind apparatus structure schematic diagram
In figure: the 1st, start-up burner, the 2nd, expansion joint, the 3rd, communication chamber, the 4th, mends 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 utility model is achieved in that below in conjunction with accompanying drawing and illustrates with the quick starting ignition combustion system of the ring low accumulation of heat of cold wind device.
See Fig. 1, the utility model is with the quick starting ignition combustion system of the ring low accumulation of heat of cold wind device, 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 being 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, on benefit wind air channel 4, be provided with damper 7, 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.In communication chamber 3, be provided with expansion joint 2, be beneficial to combustion apparatus bulk expansion.Outside with the ring low accumulation of heat of cold wind quick starting ignition combustion system device 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 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 air channel heat storage capacity, the object that realize eventually the low oil consumption of CFBB, starts fast.
