[embodiment]
The invention will be further described below in conjunction with accompanying drawing, and structure and principle that this device and method is used are very clearly for purposes of the invention.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
The present invention includes a kind of fuel supply structure that uses the low heat value producer gas, its regenerator is divided into gas regenerator and air regenerator, the effect of gas regenerator is that the heat that absorbs flue gas heats to producer gas, increase the sensible heat of heating gas, guarantee that the tarry vapours in the heating gas is not separated out.Coal gas after regenerator heating, in port with preheating after air converge, enter together the melting furnaces burning.This gas regenerator structure is the peculiar structure of burning producer gas melting furnaces.Thinking that heavy oil, diesel oil or coal dust, petroleum coke powder are in the fuel glass production line, only have air regenerator, there is not the gas regenerator.Liquid or solid fuel does not need to adopt regenerator to heat, they pass through oil pump, perhaps air-transport system is delivered to combined workshop, heat up through steam heating and electrically heated again, be heated to suitable temperature, adjust to suitable pressure, be distributed to each spray gun by tubing system again, spray gun inject fuel directly in the settling chamber of port with preheating after air mixed enter the melting furnaces burning.
Content of the present invention just is above-mentioned two kinds of different fuels are supplied with and firing system merges mutually, the latter's replenishing as the former.Namely take the burning producer gas melting furnaces as the basis, the low heat value producer gas is still as main fuel.Increase by a cover auxiliary fuel supply-system on the basis of complete heating gas plenum system.The side that the spray gun mounting means of auxiliary fuel can be on the side wall that nozzle is located at port is burnt formula, shown in Fig. 1 (a) and Fig. 1 (b); Or nozzle is located at the top-insertion type on the top arch of port, as shown in Figure 2; Formula is not inserted at the end that is located on the base plate of port of recommend adoption nozzle, and as shown in Figure 3, this is because the headroom under the little drop-bottom of furnace burning producer gas melting furnaces is little, is unfavorable for that the end inserts regular job and the maintenance of spray gun.By the effect of this spray gun, can be sprayed onto the auxiliary fuel of high heating value in the mixing system of the air of preheating and coal gas, and adjust suitable air capacity, make them enter together melting furnaces, fully burning obtains flame brightness and heat that melting process needs.The add-on of auxiliary fuel because this expensive fuel only plays booster action, is served as the coal-tar middle oil role of heating gas that bituminous coal is produced well below pure consumption take them as main fuel among the present invention, and the equipment scale of its confession match system is less also.Its additional proportion can be with envrionment temperature, and the conditions of production such as producer gas quality are adjusted.
Take a cross fire furnace of establishing six pairs of port furnace burning producer gas as example, cause in the melting furnaces temperature of fusion on the low side such as or coal gas quantity not sufficient on the low side owing to the calorific value of producer heating gas, can not satisfy normal production, at this moment can in port, replenish a small amount of higher auxiliary liq fuel or powdered fuel such as heavy oil, coal tar, diesel oil, coal dust or carbon dust, refinery coke etc. of calorific value by the mode that adds spray gun, with blackness, the raising temperature of fusion that strengthens flame.The suggestion of the spray gun mounting means of auxiliary fuel adopts side to burn formula and top-insertion type, does not insert formula at the bottom of the recommend adoption, but in case of necessity maybe this operation headroom substantially can satisfy and can adopt the slotting formula spray gun in the end to realize this purpose when spray gun operates, to satisfy Production requirement.No matter the spray gun of auxiliary fuel is installed is to adopt side to burn formula or top-insertion type, the end to insert formula, all be auxiliary fuel to be sent in the settling chamber of port by spray gun, with producer gas and combustion air pre-mixing and precombustion, further strengthen the flame radiation rate, improve the temperature of combustion of flame, to satisfy normal production.For spray gun the employing side is installed and burns formula, preferably the settling chamber with port is designed to the hydraucone shape, is convenient to side and burns the installation of formula spray gun and the flexible of angle.Horse-shoe flame furnace for furnace burning producer gas also can adopt the side shown in Fig. 4 (a) and Fig. 4 (b) to burn formula and top-insertion type as shown in Figure 5 equally, can adopt in case of necessity the end as shown in Figure 6 to insert formula.
