Novel regenerative heating furnace with reversing control device

Abstract

The invention relates to the technical field of regenerative air combustion, in particular to a novel regenerative heating furnace with a reversing control device. The novel regenerative heating furnace with the reversing control device comprises an air blower, a reversing valve, a hearth, a left gas branch pipe, a right gas branch pipe and a flue gas induced draft fan. A regenerator I and a regenerator II are arranged in the novel regenerative heating furnace with the reversing control device, and can be used for alternatively absorbing heat in flue gas and finally transferring the heat to air and gas which are not improved to enter the hearth, so that the utilization efficiency of the heating furnace to the heat is maximized. According to novel the regenerative heating furnace with the reversing control device, waste heat of the flue gas can be fully utilized, no secondary pollution is caused and relatively-high stability is realized. Besides, the novel regenerative heating furnace with the reversing control device is reasonable in structural design and convenient and quick to use and maintain, and is suitable for popularization and application.

Description

technical field [0001] The invention relates to the technical field of regenerative air combustion, in particular to a novel regenerative heating furnace with a reversing control device. Background technique [0002] Regenerative high temperature air combustion technology (High Temperature Air Combustion) is one of the most advanced combustion technologies today, which has the advantages of extreme utilization of flue gas waste heat and great reduction of NOx emissions. HTAC is a new combustion technology proposed by Japanese scholars Ryoichi Tanaka and others in the late 1980s. It uses two regenerative burners to alternately work in the intake and exhaust systems to exchange the waste heat in the furnace flue gas. For the heat storage body, the heat recovery rate in the flue gas can reach 70% to 80% of the total heat of the flue gas, which improves the energy utilization rate. Because the amount of fuel is reduced, the NOx and CO2 discharged into the atmosphere are reduced...

AI Technical Summary

Problems solved by technology

HTAC technology is characterized by energy saving, lower production costs, reduced pollutant (especially NOx) emissions, and reduced combustion noise. The common new regenerative heating furnace with reversing control device can only preheat the air to be burned. It is impossible to preheat the gas before entering the furnace, and it is impossible to make maximum use of the waste heat of the flue gas
