Position between described retort section and the body of heater is provided with secondary water-cooled casing, this water-cooled casing is the top of ring-shaped water jacket at burner hearth, described parichnos hypomere passes this pair water-cooled casing and is communicated to burner hearth, be provided with the fire exploring hole that tilts to be passed down through the water-cooled casing at this water-cooled wall box, water-cooled casing both sides are provided with water-in and water outlet.
Described body of heater is the body of heater of band water jacket, is provided with the inspection manhole that runs through water jacket and burner hearth at the sidepiece of body of heater.
Described body of heater lower sides is welded with bearing, and this bearing is fixedly connected in the pedestal by pillar.
Described deashing device comprises fire grate, is followed successively by fire grate seat, ash pan, basin, slip ring, ratchet, air blast threeway, ash pan support downwards, is provided with big grey cutter in the ash pan, and ash pan supports the bottom fixedlys connected with pedestal.
The beneficial effects of the utility model
(1) economic benefit: the production cost that has reduced enterprise.Production cost can reduce more than 20% on present basis.Enterprise has realized realizing with the less energy input target of economic growth.The lasting rising of price of fuel oil becomes a big factor that influences the business economic benefit.Compare with calorific values such as heavy oil behind the gas maked coal, cheap.After industrial furnace changed coal gas, not only fuel cost reduced, and fuel source is abundant, and easily buying is not vulnerable to external influence and restriction.
(2) social benefit: alleviated the tight relationship of coal supply and demand, dissolved the surging contradiction of industrial and agricultural products, consumer goods prices that society causes because of the coal low consumption.Combine closely, implement national economizing energy law relevant policies.
(3) environmental benefit: developing a kind of coal resources that can make full use of China's abundant, can satisfy the clean coal combustion technology of environmental requirement again, is a kind of developing direction and pressing for.The hot decoking producer gas generator of two-part is a kind of novel energy saving and environment friendly combustion equipment, not only solved the difficult problem that tar blocks pipeline effectively, and environmental protection, energy-conservation, its cost is low, excellent property, safe and reliable, processing ease especially are fit to developing country's industry and use.
