Description

Environmental protection and energy saving combustion tunnel formula hot-water boiler

A kind of environmental protection and energy saving combustion tunnel formula hot-water boiler that relates to field of boilers.

Existing middle-size and small-size combustion heat homogeneous solution-type reactor generally all is vertical or horizontal combustion heat homogeneous solution-type reactor, and coal consumption is big, firing rate is slow, area of heat-supply service is little, and the discharging flue gas is difficult to reach environmental regulations, the serious waste energy and contaminated environment.

Task of the present utility model is: provide a kind of low consumption fuel, power consumption is little, area of heat-supply service is big, firing rate is fast, the environmental protection and energy saving combustion tunnel formula hot-water boiler of novel structure, easy and simple to handle, noiselessness, no flue dust.

Task of the present utility model is finished as follows: a kind of environmental protection and energy saving combustion tunnel formula hot-water boiler, it comprises body of heater 6, drum 15, blast pipe 12, return pipe 11 that is communicated with drum 15 and outlet pipe 7, its special character is that body of heater 6 is tunnel type, body of heater 6 is provided with the fire door 13 that is connected, 14, central dividing plate 5 is set in the furnace chamber of body of heater 6, the bottom furnace chamber of central dividing plate 5 is primary zone 1, top is secondary combustion chamber 2, on body of heater 6 furnace chamber sidewalls, combined heated walls comb 3 is set, at the top of body of heater 6 furnace chamber secondary combustion chambers 2 combined thermoreceptor comb 4, return pipe 11 are set, combined heated walls comb 3, combined thermoreceptor comb 4, hot water water collector 8, outlet pipe 7 and drum 15 are connected and form a water circulation system.

Be built-in with the movable type chassis 16 of coalingging at the furnace chamber of body of heater, the chassis 16 of coalingging is inserted furnace chamber from the fire door 13 of body of heater 6, shifts out from the fire door 14 of body of heater 6.

The major advantage of environmental protection and energy saving combustion tunnel formula hot-water boiler of the present utility model is: the atmospheric gas that discharges out of the furnace during burning does not have flue dust, and noiselessness during operation, the slag of discharge are buff powder, nontoxic, tasteless, can use for capital construction; Sufficient combustion, heating surface area is big, the thermal efficiency is high, economize coal, power saving, save time, can improve heating power 1-1.5 doubly; Low cost of manufacture.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.
