Above-mentioned energy-efficient accumulation of heat tubular oven, described regenerator is two, and nozzle is positioned at the adjacent of two regenerator.
Above-mentioned energy-efficient accumulation of heat tubular oven, described regenerator is four, described reversing valve, blast orifice and air-vent are two, air and flue gas conversion mouth are two and lay respectively in two regenerator, nozzle is two and lays respectively in other two regenerator, the regenerator corresponding with two air and flue gas conversion mouth is connected with a reversing valve by pipeline, draw a blast orifice and air-vent by this reversing valve, the regenerator corresponding with two nozzles is connected with another reversing valve by pipeline, draws another blast orifice and air-vent by this reversing valve.
The utility model has the advantages that:
1, cancelled original residual neat recovering system, carry out waste heat recovery by be provided with heat storage and reversing valve in burner, air and combustion gas can enter burner hearth independently, and burning usually occurs under the oxygen deprivation state, therefore reduced the furnace oxidation scaling loss, help producing reducing flame, burner hearth is heated evenly, solved the dew point corrosion problem of original residual neat recovering system, reduced funnel temperature, funnel temperature is reduced to below 150 ℃, reduced calorific loss, improve thermo-efficiency.
2, because burner is distributed on the body of heater, can effectively prevent the too high phenomenon of local temperature in the stove, improve boiler tube surface heat intensity, can finish identical heating tasks with less heat transfer area; And then can dwindle furnace volume, economical with materials and reduction manufacturing cost reduce floor space.
3, because the interior temperature of stove is even, can reduce discharge of harmful gases such as carbon monoxide, nitride and carbide greatly, improve environment.
4, easy to maintenance, even a burner goes wrong, also can under the ordinary production situation, change.
5, the inferior fuel that can burn, low-calorie fuel can obtain higher temperature of combustion by the air of high temperature preheating, increases economic efficiency.
