Description

A kind of high accumulation of heat top combustion stove

Technical field

The utility model relates to hotblast stove, particularly a kind of high accumulation of heat top combustion stove.

Background technology

Top combustion stove is the most widely used a kind of in the present blast funnace hot blast stove, requires to have high thermo-efficiency, the purpose of, energy-saving and environmental protection efficient with final realization, raising the output; Yet hotblast stove will be realized efficient and high wind-warm syndrome, whether can reach the effect of high-intensity combustion, high duty heat transfer in mainly also being to burn and conduct heat, but because the problem that structure exists; Energy consumption is big, and wind-warm syndrome is low, and it is insufficient to burn; Poultry heat is indifferent, and heating power is unstable, thus improvement and innovate imperative.

Summary of the invention

For overcoming the prior art defective, the purpose of the utility model just provides a kind of high accumulation of heat top combustion stove to above-mentioned situation, and it is low effectively to solve wind-warm syndrome, and it is insufficient to burn, and poultry heat is indifferent, the problem that heating power instability and energy consumption are big.

The technical scheme that the utility model solves is; Comprise vaulted type combustion chamber, burner, regenerator and cold air chamber; There is columnar burner the below of vaulted type combustion chamber, from up to down has coal gas to distribute circuit and combustion air to distribute circuit in the inwall of burner successively, is evenly equipped with gasburner on the coal gas distribution circuit; Be evenly equipped with air nozzle on the combustion air distribution circuit; Gasburner and air nozzle are connected with the premix circuit of air with coal gas respectively, and coal gas has the spout that is connected with burner with the upper end of the premix circuit of air, and coal gas distributes circuit and combustion air to distribute has the gas inlet pipe and the combustion air inlet pipe of stretching out outside the hotblast stove respectively on the circuit; Below coal gas distribution circuit; Combustion air distributes the top of circuit that the hot-blast outlet pipe on the combustor sidewalls of placing is arranged, and the heat storage in the regenerator bottom that places the below is arranged in the burner, and the fire grate that places the heat storage below is arranged in the bottom of regenerator; There is cold air chamber the below of regenerator, and smoke discharge tube and cold wind inlet pipe are arranged respectively on the two side of cold air chamber.

The utility model is simple in structure, and poultry heat energy power is strong, sufficient combustion, and energy-conserving and environment-protective, the life-span is long, and is stable, and efficient is high.

Fig. 2 is that the A-A of the utility model Fig. 1 is to structural front view.

Embodiment

Elaborate below in conjunction with the embodiment of accompanying drawing to the utility model.

Provide by Fig. 1-Fig. 2; The utility model comprises vaulted type combustion chamber, burner, regenerator and cold air chamber; There is columnar burner 2 below of vaulted type combustion chamber 1, from up to down has coal gas to distribute circuit 5 and combustion air to distribute circuit 7 in the inwall of burner successively, is evenly equipped with gasburner 3a on the coal gas distribution circuit 5; Be evenly equipped with air nozzle 3b on the combustion air distribution circuit; Gasburner and air nozzle are connected with the premix circuit 4 of air with coal gas respectively, and coal gas has the spout that is connected with burner with the upper end of the premix circuit of air, and coal gas distributes circuit 5 and combustion air to distribute has the gas inlet pipe 6 and combustion air inlet pipe 8 that stretches out outside the hotblast stove respectively on the circuit 7; Below coal gas distribution circuit 5; Combustion air distributes the top of circuit 7 that the hot-blast outlet pipe 14 on the combustor sidewalls of placing is arranged, and the heat storage 9 in regenerator 10 bottoms that place the below is arranged in the burner, and the fire grate 15 that places the heat storage below is arranged in the bottom of regenerator; There is cold air chamber 11 below of regenerator, and smoke discharge tube 12 and cold wind inlet pipe 13 are arranged respectively on the two side of cold air chamber.

The bottom of described regenerator 10 is tapered to be connected with cold air chamber; Described heat storage 9 has at least two-layer, and side of the top of heat storage and spout are on same horizontal plane, and the bottom of opposite side and hot-blast outlet pipe is on same horizontal plane; The premix circuit 4 of described coal gas and air is the recessed inwall that places burner.

The utility model has improved combustion air temperature, and the effect of save energy is obvious, because self-preheating is effective; The raising of temperature of combustion and hot blast temperature is more remarkable, and coal gas and air spray through spout through the premix of the premix circuit of coal gas and air again, can realize that rapid high-intensity combustion and combustion gas flowing velocity distribution are even; Thereby effectively guarantee the operation that hotblast stove is stable, poultry heat energy power is strong, and the life-span is long; Efficient is high, and economic and social benefit is remarkable.
