Abstract
The utility model relates to a steam burning assistant device for coal burning boiler, comprising pipe lines, injection nozzles and control valves. The utility model is characterized in that one end of a general pipe is connected with a steam generator, the general pipe is provided with branch pipes, the end part of the branch pipes is provided with injection nozzles with horizontal spray orifice, and the injection nozzles are arranged under grates. The steam is guided to the lower of the grates and blows out from the injection nozzles to form a steam mist layer which comes in contact with the burning carbon, and the water-gas is generated to provide a certain amount of gas fuel to the burning layer, the thickness and the temperature of the burning layer can be enhanced, the slag temperature is lowered to prevent coking, the heat quantity that coking carries off is decreased, and the boiler thermal efficiency is enhanced.
Description
The utility model relates to a kind of boiler auxiliary combustion equipment, particularly a kind of boiler auxiliary combustion equipment that adopts water vapour as combustion-supporting medium.
No matter being civilian at present or industrial boiler, all is to have air intake vent on body of heater, forces bubbling air to carry out combustion-supporting, simple less by the combustion flame thickness that this combustion-supporting mode produced, promptly flare is shorter, and slag temperature is higher, slagging scorification easily, and loses heat is more.So the thermal efficiency of boiler is lower, the burning of coal is insufficient.
The purpose of this utility model is to provide a kind of boiler auxiliary combustion equipment of new structure, and it can overcome existing deficiency in the prior art.
The purpose of this utility model realizes by following technical proposals: the house steward that an end connects steam generator is provided with arm, and a tube end is equipped with the nozzle with horizontal spray orifice, and the master control valve is housed on the house steward, and nozzle is located at below the fire grate.
The utility model adopts water vapour as combustion-supporting medium, makes water vapour run into red-hot carbon under fire grate and generates water-gas.Upwards provide a certain amount of gaseous fuel by the burning zone bottom, realize the mixed combustion state of coal and coal gas, combine with air-breathing again, thereby improved the thickness and the temperature of the zone of flame, coal is burnt more fully, reach the purpose of saving the energy.Simultaneously can reduce slag temperature, prevent coking, reduce the heat that slag is taken away, improve the thermal efficiency of boiler.The utility model is simple in structure, be easy to processing, and cost is lower.
Below in conjunction with embodiment and accompanying drawing thereof the utility model is described in further detail.
Fig. 1 to Fig. 3 is the schematic diagram of three kinds of embodiment.
Fig. 4 is that axle of the present utility model is surveyed schematic diagram.
Fig. 5 is a kind of nozzle schematic diagram of concrete structure.
Fig. 6 is an A-A cutaway view among Fig. 5.
With reference to Fig. 1～6, introduce the concrete structure of embodiment in detail.
Shown in Figure 1 is a kind of manual fire grate.Shown in Figure 2 is a kind of traveling-grate stoker.Fig. 3 is a kind of motor-driven reciprocal grate.The utility model comprises house steward 2, arm 8 and is installed in nozzle 3 on the arm 8, and an end of house steward 2 is connected to steam generator, and the water vapour amount makes the vapor level ejection around being located at by the steam ejiction opening of master control valve 1 control nozzle 3.Nozzle 3 in the present embodiment is formed by parent 5 with by cap 6, between link with screw thread, can make the spout adjustable size like this.Parent 5 has through hole, and had blind hole by cap 6, and on wall, be drilled with through hole, the upper surface of parent 5 and all had groove by the lower surface of cap 6, water vapour enters by the blind hole of cap 6 from the through hole of parent 5, by the through hole on its wall, sprays from the formed slit of upper and lower end face groove level, by the diameter of the diameter of cap 6 greater than parent 5, so spout can not be blocked by lime-ash.Nozzle 3 also can adopt overall structure, around be drilled with spray orifice.
In order to adapt to the different needs of various combustion phases, can be on arm 8 valving 7, and the fire grate bottom is separated into a plurality of air chambers with dividing plate 4, by valve 7 quantity of steam of each air chamber is controlled respectively.
For ease of the thickness of water vapour mist under the fire grate in the observation boiler, peep-hole and lighting device can be installed, on boiler furnace according to the water vapour amount of observed result adjustment supply.
Claims (2)
1, a kind of coal-burning boiler steam added combustion device, it comprises pipeline, valve and nozzle, it is characterized in that house steward's a end connects steam generator, and the master control valve is housed, house steward is provided with arm, and a tube end is equipped with the nozzle with horizontal spray orifice, and nozzle is located at below the fire grate.
2, coal-burning boiler steam added combustion device according to claim 1 is characterized in that being equipped with on the arm by-pass valve control, under the fire grate dividing plate is housed.
