Second-ring fire combustor with blast control

Abstract

The invention discloses a second-ring fire combustor with blast control. The second-ring fire combustor with blast control comprises a control circuit board, a gas plug valve, a fire separator and an igniter; the fire separator is provided with an inner ring gas fire hole, an outer ring gas fire hole, an inner ring gas ejecting pipe and an outer ring gas ejecting pipe; and the gas plug valve is provided with a gas intake channel, a first gas exhaust channel for conveying gas to the inner ring gas ejecting pipe, and a second gas exhaust channel and a third gas exhaust channel for conveying the gas to the outer ring gas ejecting pipe. The combustor further comprises a first sensor for outputting an ignition signal when opening the gas plug valve, a second sensor for outputting a blast starting signal when the third gas exhaust channel has gas output and outputting a blast stopping signal when the third gas exhaust channel has no gas output, and an air blower for performing / stopping air blowing for the outer ring gas ejecting pipe according to a blast starting signal / blast stopping signal of the second sensor. The combustor is simple in structure, easy to realize, flexible and convenient for blast control and excellent in effect.

Description

[technical field] [0001] The invention relates to a two-ring fire burner with blast control. [Background technique] [0002] Household gas stoves have become an indispensable kitchen appliance in people's lives. Users have higher and higher demands for large firepower and convenience in firepower adjustment. However, most of the existing market products have small heat loads, and some manufacturers The thermal load of the burner is increased by means of three-ring ejection, blasting, etc., but the current structure has many defects, such as: 1. Three-ring ejection, high product cost, poor combustion conditions, and low thermal efficiency; 2. Blast burner, through the blower device to lift the air to supplement once, the blowing volume of the fan with this structure and the gas flow matching are difficult to control, when the gas changes or the gas pressure changes, unqualified combustion conditions such as flame separation and yellow flame often occur . [0003] Therefore,...
