Abstract
The present invention relates to an apparatus suitable for burning coal-water fluid, namely a coal-water fluid burner, which belongs to the field of environmental protection and energy-saving. The coal-water fluid with certain pressure and atomization air in the coal-water fluid burner are stirred by power so that the coal-water fluid is atomized and sprayed from a nozzle so as to ensure the atomization burning of the coal-water fluid and enhance burning efficiency. The coal-water fluid can be sufficiently burned so that the effects of smoke abatement and energy saving can be realized.
Description
Technical field
What the present invention relates to is a kind of coal-water fluid burner, belongs to the environmental protection and energy saving field.It can with the boiler and the supporting use of various Industrial Stoves of metabolic water coal slurry.
Background technology
Existing at present boiler for domestic, Industrial Boiler and the Industrial Stoves that burn coal all can not solve the soot emissions pollution problem, cause very big harm to environment.In order to solve the smoke contamination problem of burning coal; just tackle problems during " six or five " the clean combustion technology of research coal of China; now developed about 64% coal, 35% water and 1% chemical addition agent have been made water-coal-slurry as combustion fuel; it can thoroughly solve smoke contamination, energy savings, protection environment.But how making water-coal-slurry realize fully atomizing and burning, is the problem that need solve.
Summary of the invention
Purpose of the present invention just provides a kind of water-coal-slurry that is applicable to and makes the burner of fuel, and it can realize the burning of water-coal-slurry efficient stable, and reliable, easy to operate.
The objective of the invention is to be achieved through the following technical solutions: burner is made up of housing, atomizing air passage, water-coal-slurry passage, combustion air passage, air register and nozzle etc.In the described burner water-coal-slurry passage be located at central axis in portion, atomizing air pipeline is enclosed in its outside, and is intersected in nozzle at the port of export and water-coal-slurry passage, is cavity in the middle of the nozzle, the one end communicates with the water-coal-slurry passage, the other end is for exporting.The front end of nozzle have three evenly distribute and with the atomizing tracheae at axis angle at 45, its end communicates with cavity, the other end communicates with the atomizing air passage, the combustion air passage is enclosed in most external, in the exit of combustion-supporting passage air register is housed.
The present invention has the following advantages after adopting technique scheme: 1. cool water mixture burning thermal efficiency height; 2. flameholding is reliable; 3. has bigger load regulation range; 4. simple in structure, operation and convenient management etc.
Description of drawings
Fig. 1 is the schematic diagram of the coal-water fluid burner of proposition according to the present invention.
The specific embodiment
Below in conjunction with accompanying drawing working of an invention is described further.
As can be seen from the figure.Coal-water fluid burner is made up of housing 1, atomizing air passage 2, diffusing air-hole 3, water-coal-slurry import 4, water-coal-slurry passage 5, nozzle pulp inlet 6, nozzle 7, water-coal-slurry atomizing outlet 8, atomizing tracheae 9, air register 10, combustion air passage 11, combustion air inlet 12.In use, water-coal-slurry through water-coal-slurry passage 5, is delivered to nozzle pulp inlet 6 from water-coal-slurry import 4, enters nozzle 7.Atomizing air through atomizing air passage 2, is delivered to nozzle atomization tracheae 9 from diffusing air-hole 3, enters nozzle 7 again.The atomizing air that enters nozzle 7 stirs with the water-coal-slurry that enters nozzle 7 as Alevaire, makes water-coal-slurry reach atomizing and from jet expansion 8 ejection, realizes spray burning.For guaranteeing the abundant burning of atomized water coal slurry, combustion air enters from combustion air inlet 12, through combustion air passage 11, air register 10, guarantees sufficient combustion air by air register 10, and water-coal-slurry is fully burnt, and improves its efficiency of combustion, energy savings.Again owing to the coal-fired particle in the water-coal-slurry can be fully burned, so also reached the effect of smoke elimination and environmental protection.
