Operation principle of chain - row hot blast furnace
Chain row energy-saving hot blast furnace is a new high efficiency energy-saving hot blast furnace, the product has obtained 5 national patents.The furnace is equipped with energy-saving front and rear arches, and the back of the furnace is equipped with cyclone combustion chamber, which can ensure the full combustion of fuel and low heat loss.The principle is that the coal is sent into the furnace through the grate, and the fan provides air. Through the coal seam, the coal on the chain is fully burned and generates high-temperature flue gas. The high-temperature flame enters the secondary combustion chamber and the cyclone combustion chamber is burned again, making the flue gas blackness of the hot blast furnace lower than "Liningman 1".Chain row energy-saving hot blast furnace heating stability, high degree of automation, efficient environmental protection, safe and reliable.
Outstanding advantages of products
Advantage 1: Reduce cost, use bituminous coal as fuel, smoke black bottom is lower than "Liningman 1"
JFJN series chain row energy-saving hot air furnace is designed with coal of 5,000 CAL bituminous coal. The old earth stove requires high coal quality and must use 7,000 CAL white coal block as fuel.The furnace is equipped with energy-saving front and rear arches, and the back of the furnace is equipped with cyclone combustion chamber, which can ensure the full combustion of fuel during operation, with very low heat loss and greatly improved combustion rate of fuel.In particular, the cyclone combustion chamber setting, so that the flue gas completely combustion, heat loss is very low, so that the hot air furnace flue gas blackness is lower than "Liningman 1", to ensure that the color of the compound fertilizer produced is not affected.
JFJN series chain row energy-saving hot air furnace has small installed capacity, power consumption within 5KW-15KW and low operating cost.
Advantage 2: heat supply stability, increase the output of compound fertilizer
The chain-row energy-saving hot air furnace is automatic coal loading and grate transmission, which gives coal very evenly. When adjusting the temperature, only the damper can change the temperature. Therefore, the uniform and stable heat provided by the furnace plays an important role in the stability of the output of compound fertilizer.Temperature instability is one of the main factors affecting the yield of compound fertilizer.The output of compound fertilizer is high, the quality is good, the chain row type energy - saving hot blast furnace plays the decisive role.
Old soil the furnace temperature is not stable, the main reasons which influence the production of compound fertilizer: artificial on coal affect the temperature, temperature effect at the time of the slag, furnace heat exchange area is lesser, another old soil requires burning furnace workers must everywhere to stay in front of the stove, timely on the coal slag in time, will be affected by any carelessness caused by temperature is high or low, affect a need to change to return to normal for a couple of hours.Chain row energy-saving hot air furnace for you to solve all the above problems, to bring you high quality, high output, save effort and worry.
Advantage 3: solve compound fertilizer moisture content and caking problem
The hot air furnace has been proved by the compound fertilizer factory production test: the heating area is large, the hot air quantity is sufficient, greatly reduces the temperature difference between the head and the tail, so that the compound fertilizer water can be easily controlled within the specified range.Through the test, it is proved that JFJN series hot air furnace can control the moisture of products, solve the big problem of compound fertilizer caking, reduce the amount of anti-caking agent, and reduce the production cost.
Advantage 4: automation degree is high, reduce worker labor intensity
The three automaticity of chain row energy-saving hot blast furnace: automatic coal loading, automatic slag discharge, automatic measurement, greatly reduce the labor intensity of workers.There is no need for shovels of coal, shovels of slag, workers do not need close contact with high temperature.The old-fashioned earth stove does great damage to workers' eyes. The chain row energy-saving hot air stove is simple to operate and easy for furnace workers, which solves the problem that no one burns the stove.At the same time, the automatic metering of the chain - row energy-saving hot blast furnace solves the problem of unmetering and constant assessment.
Advantage 5: high - grade auxiliary accessories
Chain row energy-saving hot blast furnace in the production process of strict requirements, excellence, from the steel plate, grate, refractories and auxiliary accessories are regulated procurement, strict control.For example, the fire grate reducer, using BNTET 1:6,000 reducer, unit price is three times more expensive than the ordinary reducer.
Advantage six: environmental protection pollution-free, safe and reliable
The chain exhaust energy-saving hot blast furnace has been proved by repeated tests: full combustion, no black smoke, blackness is lower than "liningman 1", the combustible gas in the combustion process will be completely burned, SO2 emission concentration is lower than 900mg/m3, meet the national standard.
In addition, the chain row type energy-saving hot air furnace is non-pressure vessel, without any safety hidden trouble, easy to operate, safe and reliable.
