The lower part comprises an ash collecting chamber, a furnace wall, a gasification chamber, a grate between the ash collecting chamber and the gasification chamber and a once air inlet chamber, and the upper part comprises a burning opening, a ventilation system, a supply steam system and a control system. An outer cover is arranged on the outer side of the furnace wall, a secondary air preheating chamber is formed between the furnace wall and the outer cover, the lower part of the secondary air preheating chamber is provided with a secondary air inlet, and the upper part of the secondary air preheating chamber is led to the burning opening. The supply steam system is supplied by a circular water jacket arranged on the furnace wall of the lower part of the gasification chamber, and the upper of the circular water jacket is provided with a water supply pipe and a steam carrier pipe to the once air inlet chamber. The utility model is an independent coal gasified coal-fired burner with an integration of the supply of the steam that the coal-fired gasification needs and the burner, and has good control for preheating of the combustion air and combustion supporting wind.
Description
Technical field
The utility model relates to a kind of gasification coal-fired combusting device, belongs to the energy device of the Thermal Equipment that acts as a fuel with fire coal.
Background technology
Burner is to burn after the coal cinder gasification, and coal-fired gasifying combustion chamber originally is to be located at stove; Form indivisible integral body with stove.The steam that coal-fired gasification is required needs independent steam feedway and system.Existing coal gasification combustion device does not have secondary air and special burner, the combustion air that supplies mix bad control with coal gas, mix bad, cause the burning insufficient, flame is non-adjustable.Coal-fired gasification situation fluctuation is very big, is difficult to grasp, and therefore can form the coal-fired burning of vaporizer or gasification, burning is insufficient, causes furnace temperature fluctuation big.
Summary of the invention
The purpose of this utility model is: design independently a kind ofly, combustion air preheating, combustion air are controlled well, and the supply of the required steam of coal-fired gasification and burner are the gasification coal-fired combusting device of one.
Gasification coal-fired combusting device of the present utility model, the burner port, ventilation system, supply steam system and the Controlling System that comprise fire grate between dust collection chamber, furnace wall and vaporizer thereof, dust collection chamber and the vaporizer of bottom, an inlet air plenum under the fire grate, top, be added with overcoat in the outside, furnace wall, between furnace wall and overcoat, form the secondary air preheating chamber, the secondary air import is arranged at secondary air preheating chamber bottom, and burner port is led on secondary air preheating chamber top.
Described gasification coal-fired combusting device, supplying with steam system is to be supplied with by the ring-shaped water jacket that is located at place, furnace wall, vaporizer bottom, there is water service pipe on ring-shaped water jacket top and leads to the steam pipeline of an inlet air plenum.
Described gasification coal-fired combusting device, vaporizer top are up-small and down-big coal gas collecting chambers, and the burner port of burner shape is formed at coal gas collecting chamber top, the secondary air outlet on secondary air preheating chamber top be distributed in burner shape burner port around.
Advantage of the present utility model: whole burner is that the functions such as supply with coal-fired gasification, combustion air preheating, the required steam of coal-fired gasification become one.Having improved burning of coal efficient, reduced the content of dust in the discharging waste gas, is a kind of efficient, energy-saving and environmental protection type product.
A) the utility model is with coal gasification combustion chamber independent design, can be used as an independent system and exists, and forms single product, can form the product of stdn, seriation.
B) in order to improve flame temperature, improve efficiency of combustion, make full use of used heat, the gasification coal-fired combusting device has designed from preheated-combustion-supporting wind (secondary air), can make full use of the heat that burner distributes, realize purpose energy-saving and cost-reducing and reduction burner outer wall temperature, and can reduce operating ambient temperature greatly.
C) be collection chamber on vaporizer top, burner is formed at collection chamber top, makes coal gas and mixing of combustion air reach best effect, can make the gas-fired rate reach 100%, and the length of flame and flame propagation velocity all can be regulated by burner.Easily adopt automatic control system to regulate furnace temperature and steam air demand, guarantee that ignition energy fully gasifies.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As Fig. 1: the gasification coal-fired combusting device comprises that it is to be inlet air plenum 17, the burner shape burner port 10 on top, primary air system 14 under fire grate 3, the fire grate that dust collection chamber 1, the furnace wall 6-1 of bottom surround between vaporizer 6, dust collection chamber and the vaporizer, be added with overcoat 16 in the outside, furnace wall, between furnace wall 6-1 and overcoat 16, form secondary air preheating chamber 9, secondary air import 5 is arranged at secondary air preheating chamber bottom, the passage 15 on secondary air preheating chamber top leads to burner port 10, i.e. the secondary air of passage 15 outlet be distributed in burner port 10 around.
Supply steam system of the present utility model is to be supplied with by the ring-shaped water jacket 4 that is located at place, furnace wall, vaporizer bottom, and there is water feeding system 13 on ring-shaped water jacket 4 tops and leads to the steam pipeline 2 of an inlet air plenum 17.
Vaporizer top is up-small and down-big coal gas collecting chamber 8, the last interruption-forming burner shape burner port 10 of coal gas collecting chamber, the outlet of the secondary air of the passage 15 on secondary air preheating chamber top be distributed in burner shape burner port 10 around.
7 is stoke holes among the figure, the 11st, and Controlling System, the 12nd, thermopair.
Principle of work: thermopair detects the vaporizer temperature, and signal feedback is to Controlling System, and Controlling System is controlled ventilation system.In addition, on steam pipeline 2, be provided with the steam control device, the steam regulation operational throughput; The safety valve of detected gas pressure is arranged at ring-shaped water jacket 4 tops; Ring-shaped water jacket 4 also is equipped with water level gauge, feeds back to Controlling System, the control water feeding system.
At first fire coal is gasified in vaporizer, this vaporizer is equivalent to a small-sized producer gas generator, and its steam is to be supplied with by the water jacket that is located at the vaporizer bottom, does not need to provide separately the steam source.Required wind regime is provided by a gas blower, and the secondary combustion air is provided simultaneously.
The producer gas that produces behind the coal-fired gasification enters the coal gas collecting chamber, then by burner shape burner port with burn after secondary hot-air mixes.The angle of its burner can be regulated with the shape and the layout of stove.
