Abstract

An overall coal gasification hot water boiler that can gasify and burn the coal, and then fully burn the cinder after gasified to heat the boiler and feed water is a upright style and round boiler whose outer surface is added with a insulating layer decoration sheath wrap that mainly comprises a concrete groundwork portion (water-sealing area and an one-time air blowing area) boiler portion, (a boiler strip, a coal gas generating chamber, a sealing furnace door, a internally installed coal gas channel, a burning chamber beaming fire pipe, a dust-removing chamber and a chimney), the burning process is that: the wind crosses the furnace strip via the one-time wind chamber and enters the coal gas generating chamber and gasifies the coal, the gas passes through the internal installed pipe and enters the burning chamber and is burnt, the second-time wind helps burn, the beaming fire pipe and the dust-removing chamber discharges the water gas after collecting heat, the coke dust product after coal gasified passes through the dust-cleaning burning, heat and gas, the travelling course is unanimous, when the coke dust is burnt to the utmost the coal is placed, the furnace door is sealed, enters the next recycling passing, the two-time burning achieves the destination of clean burning and improves the utilizing efficient of the coal heat energy.

Description

The integral coal gasification hot-water boiler

Affiliated technical field

The utility model relates to, and pressure-bearing, normal pressure, series of heat homogeneous solution-type reactor combustion system especially change the direct combustion coal burning boiler into hot-water boiler that coal gasification is burnt.

Background technology

At present, the structure of known hot-water boiler is that coal directly burns, and the maximum NO of harm that discharges pollutants _xUnique can the reduction by combustion system, with gasification burner that coal gasification, conveying coal gas is too big to boiler, combustion apparatus investment, it is inconvenient to transport, store.

Summary of the invention

In order to overcome other hot-water boiler deficiency, the utility model provides an integral coal gasification hot-water boiler (pressure-bearing, normal pressure), this boiler vaporizes, enters the product after being lighted, burn, gasify in the combustion chamber with coal in generation chamber, physics sensible heat and calory burning, circulation heating is carried out in common heating boiler feedwater.

Integral coal gasification hot-water boiler of the present utility model, the overfiren air port that includes body of heater, combustion chamber and link to each other with the combustion chamber, wherein a gas generating chamber is arranged at the bottom, combustion chamber, and be connected by built-in channel between gas generating chamber and the combustion chamber, be provided with the water-stop chamber in the gas generating chamber bottom, have fire bars to be separated by between the two, primary air nozzle is communicated with closed chamber.

Above-mentioned integral coal gasification hot-water boiler, wherein built-in channel is arranged in the body of heater, and this built-in channel is by gas inlet, and gas passage and gas-fired mouth are formed, and are provided with outlet of secondary wind and coal gas ignition mouth above the gas-fired mouth.

The utility model beneficial effect is: with coal gasification, and combustion and the burning of gasification product cinder, combine, thereby reach the clean utilization coal resources, improve coal utilizaton rate, pollutant emission meets strict environmental standard, this boiler structure is simple, and is easy to operate, cost is low, the U.S. characteristics of moulding.The utility model is owing to take place coal gas to place in the same body of heater with burning, and it is big to have overcome the floor space that existing gas generator and gas furnace divide body running to bring, manufacturing cost height, unhandy defective.In body of heater, be provided with the coal gas built-in channel, the coal gas of bottom gas generating chamber generation is directly sent into the combustion chamber, top to burn, simplified furnace binding, and the heat that coal gas of high temperature can be carried absorbs directly by the water jacket in the body of heater, reduced thermal loss.
