Abstract
The utility model relates to the technical field of regenerative type combustion of industrial kilns and furnaces, more specifically to a novel air-single regenerative and air-gas dual regenerative general heating furnace. In actual production, enterprises have to reconstruct or modify a heating furnace due to change of combustion gases, which causes production stoppage losses and investment cost increase. A non-preheating gas spout is arranged between horizontal spouts (gas spouts for dual regenerator, or air spouts for single generator) of each two adjacent regenerators, and is connected with a non-preheating gas pipe network. A preheating section without a heat supply device is connected with a furnace tail flue. Such a furnace consumes various gases, which saves investment on modifying and reconstruction of a heating furnace for an enterprise.
Description
One, technical field
The utility model relates to industrial furnace regenerative combustion technology field, the two accumulation of heat general heating stoves of accumulation of heat of a kind of specifically novel air list and space gas.
Two, background technology
Gas-fired heater generally all will carry out preheating to empty, coal gas, cooperates fuel burner nozzle to carry out combustion heat supplying.The means of preheating generally adopt the heat exchanger warm-up combustion-supporting air, and temperature is at 400～550 ℃.Furnace gas is along vertically flowing on the furnace superintendent direction, by arranging bayonet-tube exchanger in the stove tail flue.The type of furnace of this heating furnace has typical bringing-up section and preheating section, belongs to gas-fired heater routinely.
The development of regenerative combustion technology is a revolution of industrial furnace technical field.Empty, coal gas carries out high-temperature heat accumulation (can reach more than 1000 ℃) by heat storage, and the whole lateral flow of inner flue gas of the stove have been broken the traditional design theory.It has efficient burning, makes full use of low-heat value gas, reduces CO
2And NO
XDischarging or the like characteristics, this heating furnace is by regenerator, heat storage, passage is formed, and is different from conventional gas-fired heater, does not have stove tail flue and tangible preheating section.
Some gaseous fuel of China is not suitable for adopting heat storage type combustion method at present.For example hot dirty producer gas, hot dirty coke-stove gas etc. owing to contain a large amount of dusts and tar in the combustion gas, cause heat storage obstruction and adhesion to harden easily, make the heating furnace cisco unity malfunction.Some high heating value gas, for example natural gas, liquefied petroleum gas or the like, the practical significance of preheating gas is little.Generally adopt the preheating of air single-preheating burning normal reheating furnace in these cases.
Some enterprise in process of production for some reason must conversion fuel gas kind.Such as changing into blast furnace gas by hot dirty gas, changing into blast furnace gas, change into natural gas etc. by blast furnace gas by the dirty coke-stove gas of heat.Its common feature is to change empty, gas double heat-accumulation combustion mode by the air single regenerative combustion system, perhaps changes into the air single regenerative mode of production by empty, gas double accumulation of heat.Therefore, because heating furnace must be reconstructed or rebuild in the variation enterprise of combustion gas kind, existing stopping production loss increases investment cost again.
Three, summary of the invention
The purpose of this utility model provides accumulation of heat of a kind of novel air list and the two accumulation of heat general heating stoves of space gas.Can save because heating furnace, the stopping production loss and the investment cost that cause are reconstructed or rebuild in the variation enterprise of combustion gas kind.
The technical solution of the utility model is the novel universal heating furnace, comprises gaspipe network, the air pipe network, soaking zone, bringing-up section, air port when gas port or single accumulation of heat during two accumulation of heat, air regenerator when gas regenerator or single accumulation of heat when air port, two accumulation of heat, air regenerator; Also have or not the preheating section of heating plant to form; During two accumulation of heat when gas regenerator or single accumulation of heat air regenerator and air regenerator be arranged in soaking zone, bringing-up section, all be intervally arranged; Between the spout of every adjacent regenerator horizontal direction (during two accumulation of heat when gas port or single accumulation of heat air port, air port), be equipped with a without preheating gas port, and be connected with the without preheating gaspipe network; Preheating section at no heating plant is connected with stove tail flue.
Specification of the present utility model:
1, on original sky, gas double thermal storage heating stove masonry structure basis, some without preheating gas ports have been increased.These spouts, supply air line and source of the gas thereof have constituted an independently gas pipe net system.This system is air feed when heating furnace needs the air single regenerative duty only, puts into operation.The system that gives gas under this coal gas system and the former pair of accumulation of heat duty is independent separately, supplies with different types of coal gas respectively.
2, heating furnace is under the air single regenerative duty, and operating whole regenerator all are air regenerators.Coal gas mixed combustion in burner hearth that preheated air and without preheating gas port spray into; When heating furnace under air, gas double accumulation of heat duty, gas regenerator and air regenerator are that consecutive intervals is arranged.Coal gas after the preheating and the air after the preheating spray into mixed combustion in the burner hearth.
3, when heating furnace is in two accumulation of heat duty, adopt sectional reversing, every section air regenerator and gas regenerator are in the synchronous communicating state; When heating furnace was in the air single regenerative duty, every section air regenerator was in commutation states, the gas port that works asynchronously with it fast shut-off or open and do not commutate.
4, this general type of furnace is provided with the preheating section and the stove tail flue of no heating plant, and it has had whole characteristics of the conventional type of furnace.Therefore, this general type of furnace combination that is the typical heat accumulating type type of furnace and the conventional type of furnace.
The utility model has the advantages that to can be enterprise because stop production loss and increase investment cost are saved in the variation of combustion gas kind, simple to operate, and be easy to control.
