Embodiment Construction

[0013] refer to figure 1 , an automatic switching regenerative gas burner, including two single gas burners with the same structure, the first gas burner 1 and the second gas burner 2 are respectively installed on both sides of the furnace body 10, the The first gas burner 1 includes a first non-heating air intake cavity 11 and a first heating air intake cavity 12, the first non-heating air intake cavity 11 is connected to the furnace body 10 through a first combustion chamber 13, and the first heating The air intake chamber 12 communicates with the first heat storage body 15 , and the first heat storage body 15 communicates with the furnace body 10 through the first air and flue gas passage 14 . The structure of the burner is simple and compact, the gas can enter and exit freely, and the heat exchange is sufficient, which greatly increases the intake temperature of the combustion-supporting air and reduces the exhaust temperature of the flue gas, so that the combustion is com...

Abstract

The invention provides an automatic-switching heat accumulation type gas burner, wherein two single gas burners with the same structure are arranged at two sides of a furnace body; when one burner burns, the other burner accumulates heat; the automatic reversing of the burner is achieved by an external switching valve; the switching of a low-temperature operating mode and a high-temperature operating mode, the low-temperature high-speed burning and the high-temperature oxygen-lacking burning and smoke reflux technology are adopted, so that the heat exchange is full, the inlet temperature of the combustion-supporting air is improved greatly, the temperature of the exhausted smoke is reduced, the complete burning is achieved, and the low NOx emission, automatic switching of high and low temperature operating modes, high-efficient and energy-saving self heat accumulation function are achieved.

Description

technical field [0001] The invention relates to a regenerative burner, in particular to a self-regenerative gas burner with compact structure, complete combustion and low NOx emission. Background technique [0002] The technical key of high-air temperature and low-oxygen combustion lies in preheating the combustion-supporting air from room temperature to a high temperature of 800-1100°C through several pairs of high-efficiency regenerators that work alternately, and at the same time effectively organizing the flow rate and intersection angle of the fuel and combustion-supporting air into the furnace. , mixing methods and other means, so that the fuel can be burned in volume in the furnace space where the oxygen content is controlled at 2~15%, so that the NOx emission can be greatly reduced. Controlled within the range above the dew point and below 150°C, this advanced combustion method can simultaneously achieve the effects of environmental protection, energy saving, and hig...
