Abstract
The invention relates to a method for improving temperature of primary air of a gas producer. The method is characterized by comprising the following steps: extracting high-temperature air from a dog-hole part of a running glass kiln; conveying to a primary air fan inlet of the gas producer through a pipeline of phi500mm; and pressurizing the air by the fan, and then directly introducing the air into a gas furnace to participate reaction so as to accelerate the combustion reaction rate, so that the gasification temperature is improved; and gasification reaction of coal is facilitated, so as to save fire coal.
Description
Technical field
Patent of the present invention relates to a kind of method improving producer gas generator First air temperature.
Background technology
Each uses producer gas generator to manufacture the manufacturing enterprise of mixed gas at present, the vaporized chemical of producer gas generator, combustion air are all normal room temperatures, air preheating in burner hearth will consume a large amount of heats, reduce gasification efficiency and charcoal percent conversion, cause carbon content in lime-ash relatively high, reach about 20%, add consumption of coal.Occupy this kind of situation, we adopt the method improving producer gas generator preheated air temperature to improve charcoal percent conversion.
Summary of the invention
The object of patent of the present invention is to provide a kind of method improving producer gas generator First air temperature, it is characterized in that, comprises following methods:
Step one, install coal cinder additional
Be added to by coal cinder in producer gas generator, the Task-size Controlling of described coal cinder is at 15 ~ 100mm; Coal is brown coal, and calorific value is at about 3500kcal/kg.
Step 2, preheated air
Near glass furnace dog-hole, be installed into air port, blast inlet is of a size of φ 600mm ~ φ 750mm, and the pipeline installing φ 500mm in blast inlet 90 ° of directions is connected with producer gas generator primary air fan entrance.The centrifugal blower installing a 3kw on the opposite of blast inlet additional forces cooling kiln furnace hearth wall, dog-hole is made to obtain cooling, the warm air of its periphery is also got air port simultaneously and is taken away, the air themperature of getting air port place after testing can reach 120 ~ 180 DEG C, and the air themperature arriving producer gas generator primary air fan ingress can reach 50 ~ 70 DEG C;
Step 3, gas furnace run
Gas furnace operating parameters controls: gas exit pressure: 100 ~ 250Pa
Gas outlet temperature: 150 ~ 250 DEG C
Pressure of blast: 0.8 ~ 1.5Kpa
Saturated air temperature: 60 ~ 80 DEG C.
Described 3M13 type atmospheric fixed bed gas-producer.
Described method makes the efficiency of carbon conversion of coal be improved about 15%.
Former 53m
2glass furnace molten glass every day liquid 110 tons, consumption of coal about 51.5 tons/day, after using the method, when every day, molten glass liquid tonnage number was constant, consumption of coal reduces to 42.3 tons/day, and average every day saves coal-fired 9.2 tons.
The object of the invention is to improve First air temperature, accelerate combustion rate, thus improve gasification temperature, be convenient to coal gasification reaction, thus it is coal-fired to reach saving.
Beneficial effect:
1, cooled glass kiln pool wall and dog-hole, extends kiln work-ing life.
2, by improving producer gas generator primary air fan temperature in, coal gasification efficiency is increased.
3, improve the efficiency of carbon conversion of coal, save coal consumption.
