Another purpose of the present utility model provides a kind of coal water combined combustion boiler that has the new combustion chamber of guide and steam joint.
Another purpose of the present utility model provides a kind of coal water combined combustion boiler of the pipeline that water tank, water jacket furnace wall, spray vapour dish can be coupled together safely.
Another purpose of the present utility model provides the material of making in to make new moulded coal water combined combustion boiler.
According to coal water combined combustion boiler of the present utility model, except by the combustion chamber of conventional boiler, go up lower furnace door, furnace shell, base, burner hearth and the blower fan, be provided with a triangular ring water tank and water supply assembly thereof in the bottom, combustion chamber, the annulated column shape water jacket furnace wall and following furnace wall that is attached thereto and the furnace wall insulation material that communicate with water tank, double-layer grate at the bottom of the shove charge thorax, be clipped in the middle spray vapour dish of double-layer grate, the connecting tube that connects water tank and water jacket furnace wall, the connecting tube that connects water jacket furnace wall and spray vapour dish is formed.
Inwall according to the combustion chamber of coal water combined combustion boiler of the present utility model is provided with 3～7 arc guide pieces, and the outer wall of combustion chamber, the top of water tank are provided with steam joint.The outside of water tank is provided with the water level meter.
According to coal water combined combustion boiler of the present utility model, the connecting tube that connects water tank and water jacket furnace wall is made up of shutter, non-return valve, elbow, short tube.The connecting tube that connects water jacket furnace wall and spray vapour dish is made up of institutes such as Pressure gauge, ball valve, loose joint, elbow, short tubes, is provided with a safety valve in this connecting tube.
According to combined combustion boiler of the present utility model, combustion chamber, upper and lower fire door, furnace shell, water jacket furnace wall, base etc. can be ironcastings, also can be welded with steel plate.
According to coal water combined combustion boiler of the present utility model, from the upper furnace door burner hearth of packing into, new water is by the water tank of packing into to water assembly with coal, via shutter and non-return valve, enter the water jacket furnace wall, water and steam, spray in the coal in the burner hearth to spray vapour dish by the ball valve loose joint.Pressure gauge demonstrates the steam in the water jacket furnace wall and the pressure of water, and during hypertonia, safety valve will discharge too high pressure, and the water level meter on the water tank demonstrates the water level in the water tank, so that in time add new water, also can outwards supply with steam by steam joint.
According to coal water combined combustion boiler of the present utility model, the thermal efficiency can reach more than 80%, can save burning more than 50%.Both can be used for cooking, heat supply water, but heating again.
According to coal water combined combustion boiler of the present utility model, rational in infrastructure, supply with combustion-supporting steam by the water jacket furnace wall to spray vapour dish, coal can fully be burnt, produce CO and H2 simultaneously and also participate in burning, owing to be provided with the spring loaded safety valve of adjustable pressure, carry out open port firing, can guarantee safety, pollution-free, environmental protection standard is 0～1 grade of Lin Geman.
According to coal water combined combustion boiler of the present utility model, compare with the boiler of equal capacity, can save operating cost more than 50%.
