Abstract

The invention provides an environment-friendly air and liquefied gas premix burner which essentially comprises a burner nozzle and an air and liquefied gas premix device which comprises a burner shell and a mixed gas filter which is positioned in the shell and comprises an upper filter tray and a lower filter tray which are provided with a plurality of holes at proper intervals; the middle part of the burner shell is tubulose while the upper part is slightly wider and embedded in the burner nozzle and the lower part is a prominent small pipe which is the inlet of liquefied gas and air; the burner nozzle comprises homocentric rings which are composed of straight strip belt material and obstructed from each other by wavy belt material, and also comprises a positioning plate which is sheathed on the air and liquefied gas premix device, and on which a cresset with an ignition tube is fixed, and a burner cover which has a center hole and a projecting end and is sunk in inner face and covered on the burner nozzle and the cresset. The air and liquefied gas premix burner of the invention has simple structure, lower noise generated in the production, less gas consumption, is environment-friendly and energy saving and shows good performance.

Description

technical field [0001] The invention relates to the field of cooking equipment, more specifically to the field of burners, in particular to an environment-friendly premixed burner of air and liquefied gas. Background technique [0002] In existing batch cooking equipment or Chinese / Asian cooking equipment, chefs widely use mixed air and liquefied petroleum gas burners (cast iron type burners with refractory bricks inside, called air blowtorches in some countries) burner)), this air blowtorch in many Chinese and / or Asian cooking kitchens requires a blower to activate and accelerate the fire for batch cooking and quick cooking. Although this type of air blowtorch has a strong firepower, it produces a lot of sound pollution. It can produce 93dB level noise during the combustion process, causing serious sound pollution problems in the kitchen area, and consumes a lot of energy. It can consume 204750BTU / hours (60 kW) of heat input. Contents of the invention [0003] The main...
