Abstract
The invention develops a new combustion system fore each kind of industrial furnace, the system uses coal as fuel, uses the coal gas generating furnace to gasify the coal and flows them into the industrial furnace after being heated, because using the gas fuel, the industrial furnace may uses the advanced heat reservation combustion mode, namely: it integrates the direction changing combustion and the heat reservation combustion into a body. It combines the coal gas generating furnace and the industrial furnace, realizes the connection of gasifying process and the combustion process. Thus we call it as fuel coal gasifying heat reservation and combustion system.
Description
Affiliated technical field
The present invention is directed to various industrial furnaces and researched and developed a new combustion system, this system acts as a fuel with coal, directly infeed industrial furnace after utilizing gas generator to make coal gasification and heating, owing to used gaseous fuel, industrial furnace can adopt advanced heat storage type combustion mode, that is: the burning of collection commutation type is an one with the heat-accumulation type hot recovery system.The hot blast while after the accumulation of heat is as the combustion adjuvant of industrial furnace and gas generator.It is the combination of gas generator and industrial furnace, has realized the organic linking of the heat storage type combustion process of the gasification of coal gas and industrial furnace.We are called this system " coal-fired gasification regenerative combustion system ".
Background technology
The energy reserve coal of China accounts for more than 60%, and for effectively control burning of coal process and minimizing are to the pollution of environment, the coal gasification burning will be the important directions with coal.With regard to the coal gasification technology, technology is all ripe both at home and abroad at present, and gas generator also is applied in the industrial production stove in large quantities, and the gas generator part of the present invention's design will utilize prior art to finish.Accumulation of heat reversing combustion technology is the most energy-conservation combustion system that present industrial furnace adopts, and just is being tending towards ripe, has obtained especially in recent years applying fast.But the just present domestic and international information that we are grasped is united the also not application of complete combustion system of formation with gas generator and heat-accumulating industrial furnace.The coal-fired gasification regenerative combustion technology that this invention proposes still belongs to the first time.
Summary of the invention
The formation of industrial furnace coal-fired gasification regenerative combustion system derives from the ingenious design to this system.Gas generator and industrial furnace are united formation one burning integral body, and heat exchange type combustion technology and heat accumulating type heat recovery technology organically are applied to this system, both constituted " coal-fired gasification regenerative combustion system ".
The technical scheme that technical solution problem of the present invention is adopted is:
1, in combustion system of the present invention, finishes the heat accumulating type reversing combustion by two reversing arrangements.One is air flue gas commutator, solves the accumulation of heat commutation problem of industrial furnace.Another is the coal gas dust removal commutator, and the coal gas that the solution producer produces infeeds the dedusting commutation problem in the industrial furnace system.
2, adopt the water seal commutation not only to finish the dedusting of hot dirty gas, finished the coal gas commutation problem of whole combustion system simultaneously.
3, utilize the hot blast that a certain regenerator produces in the industrial furnace, the hot dirty gas that produces for producer is heated to more than 600 ℃, makes the tar gasification, directly the coal tar in the coal gas is burnt, and has increased the calorific value of coal gas, has solved the problem of coal tar coking.Secondly the waste heat of hot blast utilizes the combustion air as producer once more, makes gas generator combustion-supporting down at hot blast, improves the output and the gas quality of producer.
4, regenerator can be arranged under the furnace wall or outside the furnace wall according to different Thermal Equipments.
The invention has the beneficial effects as follows that coal gasification combustion is a cleanest coal-fired combustion method, efficiently solves the pollution that caused by coal burning problem, simultaneously, producer gas is the necessary condition that realizes the industrial furnace heat storage type combustion; The industrial furnace regenerative combustion technology makes full use of the waste heat of flue gas, makes the industrial furnace waste heat recovery near the limit.This combustion system will make the coal-fired industry furnace system obtain doulbe-sides' victory aspect energy-conservation and environmental protection two.
Description of drawings
Below in conjunction with accompanying drawing this combustion system is described further.
This combustion system constitutes complete combustion system by gas generator system and industrial furnace regenerative combustion system by air flue gas commutator and coal gas dust removal commutator.Fig. 1 has provided the preceding coal gas of commutation, air, flue gas flow.Fig. 2 has provided commutation back coal gas, air, flue gas flow.
The specific embodiment
It is to enter industrial furnace body after the commutation preheating by coal gas, air to finish high-temperature air burning that native system constitutes (seeing Figure of description 1 and accompanying drawing 2) and realization.The path of coal gas, combustion air and flue gas is:
The coal gas path: the hot dirty gas that is produced by producer becomes clean gas and enters the heating of gas piping heater behind the coal gas dust removal commutator, coal gas is heated to more than the coal tar gasification temperature, infeeds industrial furnace.
Combustion air path: by the combustion air that air blast infeeds, behind air, flue gas commutator, enter the regenerator of industrial furnace one side, enter after more than accumulation of heat to 1000 ℃ in the industrial furnace and coal gas mixed combustion.
The flue gas path: the flue gas that produces after the industrial furnace internal combustion is through industrial furnace opposite side regenerator, and behind the heat storage in himself heat transferred regenerator, flue-gas temperature is reduced to below 200 ℃, drains after air, flue gas commutation.
