Embodiment Construction

[0020] The working principle and structure of the external combustion type regenerative heating furnace of the present invention are as follows: figure 2 As shown, the structural characteristics of the external combustion regenerative heating furnace can be seen from the figure. The external combustion type regenerative heating furnace 109 is an upright cylinder with a hemispherical top. The inner wall is made of refractory bricks 110, the outside is covered with steel plates 111, and the furnace cavity is filled with checker bricks 113. During production and operation, coal is fed from the hopper 101 arranged above the front side of the dry gas furnace 105, and fed to the chain grate 103 through the feeder 102, and the coal burns on the chain grate to generate high-temperature flue gas, reaching 1100 °C As mentioned above, the high-temperature flue gas is drawn from the upper rear of the dry gas furnace 105 through the discharge pipe 106, and the low-temperature flue gas mi...

Abstract

The invention discloses an external combustion regenerative heater, which is characterized in that: a combustion chamber is arranged outside the regenerative heater, and the thermal efficiency, the safety and the adaptability are high. The external combustion regenerative heater can be applied to heating various combustible gases and incombustible gases, including air, nitrogen, carbon monoxide, carbon dioxide, hydrogen, methane, gas, coal gas, natural gas and the like. The fuel can be coal, oil shale and other solid fuel, also can be burning oil and other liquid fuel, and also can be coal gas, gas, natural gas and other gas fuel.

Description

technical field [0001] The invention relates to a device for heat storage and heating of heated gas in a heat storage furnace by using an external combustion method. Background technique [0002] Regenerative heating furnace is a device that uses advanced heat storage technology to heat heat carrier. It has the advantages of compact structure, large heat exchange area, high thermal efficiency and long service life. It is widely used in metallurgical industry, machinery industry, chemical industry, oil shale dry distillation and refining industry. Most of the regenerative heating furnaces currently used in industrial production are internal combustion. Regenerative heating furnaces can be divided into three types according to their combustion methods: top-firing type, bottom-firing type and side-firing type. The process flow is to introduce coal gas and combustion-supporting air into the combustion chamber of the regenerative heating furnace for combustion, and the high-tem...
