Problems solved by technology

During construction, the gas and air channel formwork in the furnace wall must not only ensure the design size of the furnace wall, but also consider the removal of the formwork after construction (because the channel section is too small, the operator cannot enter at all), so the air (flue gas) 1. The support and removal of the gas channel formwork is the key process of furnace wall construction. The support and removal of the formwork is relatively difficult, that is, the burners, air channels, and gas The construction method of the channel is complex and difficult

Embodiment Construction

[0014] As shown in Figure 1 and Figure 2, the regenerative heating furnace adopts the existing waste heat self-recovery industrial furnace, and the furnace walls on both sides of the regenerative heating furnace are arranged in groups of burners, air channels, and gas channels; Among Fig. 1, Fig. 2: 1-furnace wall, 2-air channel (flue gas channel), 3-coal gas channel, 4-burner.

[0015] The construction method of the burner, the air channel and the gas channel in the furnace wall of the regenerative heating furnace includes the following steps:

[0016] 1). According to the design dimensions of the burners, air passages and gas passages in the furnace walls on both sides of the regenerative heating furnace, draw the template diagram of the burners, air passages and gas passages in the furnace wall; make the burner with PVC material according to the template diagram. The cavity formwork of nozzle, air channel, gas channel (as shown in Figure 3, burner cavity formwork 6 and air ...

Abstract

A method for constructing nozzle mouth and air channel as well as gas channel on wall of thermal storage heating furnace includes plotting out template drawing of nozzle mouth and air channel as well as gas channel according to their sizes on said wall then preparing cavity template by PVC material as per said template drawing, transporting their cavity templates into their positions on two sides of said wall and fixing them there, pouring fireproof material then self burning said cavity templates prepared by PVC material for forming nozzle mouth and air channel as well as gas channel.

Description

technical field [0001] The invention relates to a construction method for a burner, an air passage and a gas passage in the furnace walls on both sides of a regenerative heating furnace. Background technique [0002] Regenerative high-recovery heat exchange technology is an advanced energy-saving and environmentally-friendly technology that is promoted by the state. Patent No. 92238591.2, and the patented technology named "Full Self-Recovery Waste Heat Industrial Furnace" has been gradually promoted and used. With this technology, the air (coal gas) can be preheated to only about 100°C lower than the furnace temperature to participate in combustion, and the exhaust gas discharge temperature is only 150°C. This type of furnace adopts the domestic original combination of heat storage tank and group burner, so that the combustion flame forms a fire curtain, flows and rolls in the furnace, forming a seamless pattern from the furnace wall on both sides to the furnace top and furn...
