Abstract

The invention discloses a hot air type combustor. The hot air type combustor comprises a fuel butterfly valve, an air ventilation door, an adjusting mechanism assembly, a cooling air inlet and a combustor shell. The combustor shell comprises an outer shell body, an inner shell body and non-asbestos alumina silicate fiber cotton. An ignition needle device comprises an ignition needle and a ceramic bar installed outside the ignition needle. The bottom of the air ventilation door is connected with a ventilation door assembly. The ventilation door assembly comprises a ventilation door frame, a ventilation door shaft, a temperature sensor and a servo adjusting motor. The combustor shell is further provided with a fire detection thermal insulation sleeve. The fire detection thermal insulation sleeve comprises a flame monitor and a thermal insulation glass cover. A combustion head adjusting barrel assembly is arranged behind the fuel butterfly valve and comprises an air pressure adjusting barrel, an adjusting pull rod and a fuel gas mixing head. The hot air type combustor achieves the aim of temperature resisting of the ignition needle and the flame monitor, the temperature of the outer surface of the combustor is reduced, and pressure adjustment on the ventilation door and the fuel combustion head of the combustor can be automatically carried out along with the temperature change.

Description

technical field [0001] The invention relates to a burner, in particular to a hot air type burner. Background technique [0002] The current society is paying more and more attention to energy saving and emission reduction, and national standards also mandate that the exhaust gas temperature of industrial boilers be controlled within a reasonable range. For boilers with a higher temperature of the heated medium, to reduce the discharge temperature of the exhaust gas, it must be equipped with a secondary heat exchange device to recover heat. The secondary heat exchange medium can be water or air. For some industrial production sites, especially heat-conducting oil furnaces, hot water cannot be used, so only air can be heated, so hot air burners come into being. [0003] The hot air type burner means that the combustion-supporting air required by the burner is high-temperature air, and some are even heated to 250°C. Because the burner is a mechatronic device, some electrical...
