A high-efficiency energy-saving environmental protection preheating type internal flame burner

Abstract

The invention discloses an energy-efficient environment-friendly preheating inner flame type burner. The energy-efficient environment-friendly preheating inner flame type burner externally comprises a burner casting shell (4) and a burner casting base (11), wherein a small fire channel is arranged at the lower end part of the burner casting base (11), and forms a seed fire supply device with a small fire air regulating valve (12) arranged on the outer end of the bottom of the burner casting base (11) and a small fire regulating valve (14), the top end of the interior of the burner casting base (11) comprises an interlayer ring top cover (3) which comprises a main fire burner igniting inner ring (5) at the upper end part and a small fire burner (8) at the lower end part which form a burning system, an outer layer space ring (7), a middle layer space ring (6) and a burner casting base (11) and an inner cavity of a burner casting shell (4) can form a combination gas preheating circulating system, and an ignition and flame detection needle (9) at the edge of the lower end of an inner cavity of the main fire burner igniting inner ring (5) serves as a control device. The energy-efficient environment-friendly preheating inner flame type burner provided by the invention has the advantages that the effective heat efficiency of the burning is strengthened on the aspect of design structure, and a backward condition that the traditional blowing-type burner can operate with high load and low efficiency is thoroughly solved.

Description

technical field [0001] The invention relates to a burner system in large-scale commercial kitchen equipment, business groups and industrial combustion equipment, in particular to a high-efficiency, energy-saving, environment-friendly, preheating type internal flame burner. technical background [0002] At present, domestic large-scale commercial kitchen gas equipment and burner systems in business groups generally use traditional cast iron trench furnaces equipped with high-power fans in the furnace for forced blast combustion or semi-premixed combustion for relatively backward combustion. They all use gas and air to enter the burner in the furnace respectively through pipelines, and enter the furnace cavity from the bottom of the burner for mixed combustion to achieve strong combustion under high-load conditions. However, this method has never been able to solve and overcome the problem that the extremely hot and high temperature generated by the combustion will be quickly ...

Problems solved by technology

However, this method has never been able to solve and overcome the problem that the extremely hot and high temperature generated by the combustion will be quickly absorbed by the burner head itself. In severe cases, the burner head will be forced to produce gas tempering and burns due to excessive heat transfer temperature. Deflagration hazard

Especially for the traditional forced-air all-cast iron burner, it consumes a lot of energy, and the emission value of harmful substances in the flue gas is also high, so the harm of serious pollution to the atmosphere increases, and the combustion noise is very loud.

What's more, because gas and air are remixed at the outlet of the burner head fire hole, uneven mixing of gas and air and insufficient combustion will occur, so that cooler air is directly mixed with gas in the furnace. This method is the main reason for the very low thermal efficiency of combustion because the combustion temperature of the gas is also reduced during the collision process of the gas mixture when the gas is diluted by the cold air.

[0004] At present, semi-premixed or general fully premixed combustion methods are still used in the market to achieve high-load combustion products. After analysis, the complete combustion effect has not yet been achieved, which makes the improvement of combustion thermal efficiency unsatisfactory, and it is difficult to achieve the energy efficiency standard of high efficiency peak. Moreover, it cannot fully solve the comprehensive indicators of rapid heating of the burner head and low emission of harmful substances in the flue gas, low noise, high efficiency, energy saving and consumption reduction, and greenness, safety and environmental protection.
