Commercial high-power efficient environment-friendly flameless infrared kitchen core

Abstract

The invention discloses a commercial high-power efficient environment-friendly flameless infrared kitchen core, which belongs to the field of gas appliances and aims to provide a kitchen core with high thermal efficiency. The technical key points are that: the kitchen core comprises a cylindrical outer shell, a bowl-shaped inner shell in the cylindrical outer shell, and an annular flame path which consists of a refractory central column and a refractory outer ring; the bottom of the refractory central column is provided with an ignition structure which consists of a windproof bowl, a central kindling fuel gas sprayer, a central kindling fuel gas mixer and a central fuel gas inlet pipe; a main fuel gas distributor is positioned below the windproof bowl, and a circle of fuel gas spraying holes in the bottom of the main fuel gas distributor are opposite to a main wind inlet; a fuel gas channel formed by the inner wall of the outer shell and the outer wall of the bowl-shaped inner shell is divided into a first mixing channel and a second mixing channel by the side wall of a bowl-shaped narrow gap premixer, and secondary mixed gas mixing notches are distributed at the upper end of the bowl-shaped narrow gap premixer; and a plurality of tertiary mixed gas mixing spraying holes with different inclinations and entering chamfers are distributed in the side wall of the bowl-shaped innershell on the lower part of the annular flame path. The commercial high-power efficient environment-friendly flameless infrared kitchen core is mainly used for heating and processing food in hotels, restaurants, dining rooms, mess halls and the like.

Description

technical field [0001] The invention relates to a gas stove, more specifically, it relates to a commercial high-power, high-efficiency, environment-friendly flameless infrared stove core. Background technique [0002] Gas cooking stoves used in hotels, restaurants, restaurants, and canteens require concentrated firepower, high local heat intensity at the bottom of the wok, and fast heating speed. Both large pot stoves and steam cabinets require large heat loads (output power). At present, the vast majority of domestic commercial gas cooking stoves and steaming cabinets use blast swirling or "premixed" stove core burners with a heat load flow of 50-70KW. These two kinds of burners all have following deficiencies: [0003] 1. Blast swirl burner: It belongs to the traditional diffusion combustion method (post-mixing combustion). The "Cantonese stove" is the standard on the market, and "Wuxi stove" and "Shandong stove" have appeared one after another, but their burning methods...

AI Technical Summary

Problems solved by technology

Insufficiency of existing products: the depth of premixing is difficult to increase due to structural limitations, and complete premixing and complete combustion cannot be achieved

The products on the market are all large-diameter varieties, and the small-diameter 4-5 inch heat load flow can only reach 1.55-6.4KW, the heat flow is too small, not suitable for Chinese food frying stoves, etc.
