In addition, at present employed full gas boiler is comparatively stable under the normal combustion state, but it is missing of ignition to have existed igniting before use early, igniting evening dangerous and catch fire before the disadvantage of over-emitting black exhaust, it is insufficient to burn, thermal losses is big.
The utility model has overcome the deficiency of above-mentioned prior art, and its purpose is to provide a kind of environment protection type energy saving boiler.
The technical solution of the utility model is achieved in that
A kind of environment protection type energy saving boiler, what comprise the fire grate, combustion chamber, heat exchanger, air distribution device and the boiler that are arranged in the ordinary pan body of heater adds coal stove door and scarfing cinder fire door, it is characterized in that being provided with in the said boiler body two or more separate combustion chambers, be provided with intermediate bulkheads between per two adjacent independent combustion chambers.Do not go here and there fire between two adjacent combustion chambers mutually, can be respectively or ignite simultaneously and recycle.Above-mentioned next door can adopt the metal plate type hot switching path to make the water-cooled next door, and two combustion chambers are isolated mutually; Also can adopt and build refractory brickwork between the water cooling tube by laying bricks or stones and make the water-cooled next door, two combustion chambers are isolated mutually.Above-mentioned metal plate type hot switching path or water cooling tube are connected with boiler water, and its outer wall surface is provided with refractory material.
Because what the utility model was taked is the upper-burning combustion system, lights a fire, and sends into wind below fire grate one time, after igniting, the upper surface coal seam sends into secondary wind to the combustion chamber, the reverse from top to bottom burning of high-temp combustion layer of the very fast formation in surface, coal seam above the coal seam.Form gas-fired for carbon body when burning of making coal is can be in the combustion chamber inner, be provided with water storage room below the fire grate of this boiler, and in water storage room, be provided with air distribution device one time.Under a wind stirred, the high temperature fixed carbon in formed water vapour of the water in the water storage room and the fire coal produced chemical reaction, and part has formed gas-fired.
The utility model is owing to be to take the upper-burning combustion system; Whole combustion process is in high temperature very hot oven state all the time, owing to formed the combustion system of upper-burning at the very start, the Lin Geman phenomenon that exceeds standard can not occur discharging fume so bank up a fire from igniting or blowing out midway, and smoke evacuation Lin Geman is in about 0~0.5 grade of level always.Because combustion system is different with original combustion system, phosphorus content reduces significantly so this boiler is slagged tap, and heat loss is little, compares effect of coal saving with plain cylindrical furnace and can reach 35~40%, improves the thermal efficiency more than 30%.Boiler provided by the utility model dedusting voluntarily, ash and slag disposal is all very easy, fire-sealing time is long, it is convenient to change coal, two combustion chambers (small-sized) can successively light a fire, recycle, disposable throwing coal can burn about 5~7 hours, had alleviated fireman's labour intensity greatly, was present a kind of comparatively ideal environment-friendly and energy-efficient product.
