Problems solved by technology

[0005] The inner flame gas stoves seen on the market have double rows of circular fire holes on the conical surface of the inner circle of the burner top. In doing so, although the area of ​​the fire holes can be increased by increasing the number of fire holes, due to structural limitations, It is difficult to supplement the air between the upper and lower fire holes, and the improvement of heat flow is still difficult to meet the market demand

Embodiment approach

[0042](1) Implementation mode of the single-cavity fire distributor device without air passages between the fire holes on the upper layer

[0043] Implementation of the first exemplary embodiment:

[0044] On the fire distributor device 2, upper and lower layers of fire holes 301, 302 are provided along the circumference of the inner ring, and the fire hole outlet direction is inward; The height direction of the conical surface sections is single row or double row or multiple rows distributed along the circumference, and the section of the fire hole is circular; the lower fire hole is arranged at the bottom of the cylindrical section 304 of the inner ring of the main body of the fire distributor; the section of the fire hole is trapezoidal; The layer fire hole communicates with the internal cavity 305 of the main body of the fire distributor, and the conical surface section of the inner ring of the main body of the fire distributor is directly connected with the cylindrical se...

Abstract

The invention discloses a multilayer inner flame combustor which consists of a combustor body and a distributor device, two fire orifice layers of an upper layer and a lower layer are arranged on the distributor device, and fire orifice outlets are arranged inwards; air channels are arranged or not arranged between fire orifices in the upper layer; a single inner chamber or two independent inner chambers are arranged; the two independent inner chambers are arranged so as to independently adjust flame in the upper and the lower layers; the air channels are arranged so as to lead air supplement to be more sufficient. The multilayer inner flame combustor is characterized by double-layered cyclonic flame, large heat transfer rate, high thermal efficiency, low CO and NOx content in flue gas and unblocked fire orifices, and the like, and can be widely used in inner flame gas cookers.

Description

technical field [0001] The invention relates to a burner for a gas stove, in particular to a multi-layer inner flame burner. Background technique [0002] In recent years, internal flame gas stoves have been paid more and more attention to because of their high thermal efficiency and gas saving. However, there are few internal flame gas stoves with a heat flow greater than 4kW on the market at present, which is difficult to meet people's demand for large firepower internal flame gas stoves. [0003] To increase the heat flow of the gas stove, the most direct way is to increase the burner area by increasing the number of fire holes to meet the needs of increased heat flow. Of course, the prerequisite is to ensure good combustion conditions and good combustion conditions. Harmful gases in the flue gas cannot exceed the standard. [0004] The burner used in the inner flame gas stove has a trapezoidal, rectangular, strip or circular cross-section of the fire hole, and the fire...
