Totally upward air inlet combustor

Abstract

The invention relates to a totally upward air inlet combustor which comprises a combustor base, an injection module, a main fire dividing assembly and a center fire outlet cover. A main fire dividingcavity is formed in the main fire dividing assembly, the injection module is arranged on the combustor base and comprises a center fire injector, a main fire injector and a horizontal partition plate,and a main fire air outlet end of the main fire injector communicates to the main fire dividing cavity; a main fire air inlet end of the main fire injector is fixed to the lower surface of the horizontal partition plate, and the main fire air outlet end of the main fire injector penetrates the horizontal partition plate and communicates to the main fire dividing cavity; a center fire air inlet end of the center fire injector is fixed to the upper surface of the horizontal partition plate; a vertical partition plate is fixed to the horizontal partition plate, the vertical partition plate is arranged behind the end surface of the center fire air inlet end of the center fire injector, the upper end surface of the vertical partition plate is in contact with the lower surface of the main firedividing assembly, and two ends of the vertical partition plate stretch to two sides of the end surface of the center fire air inlet end of the center fire injector. The totally upward air inlet combustor is compact in structure, good in stability, high in combustion power and high in working reliability.

Description

technical field [0001] The invention relates to a complete upward air-flow burner. Background technique [0002] At present, in the gas cooker and integrated stove industry, most of the burners use the bottom-inlet combustion technology. Although some are upward-inlet, they are based on the bottom-inlet burner, and the burner head is lifted. In order to realize the supply of secondary air from the top of the panel, but the supplement of primary air does not realize the upward air intake, so it cannot be called a complete upward air intake technology. And when the burner is applied to an ordinary gas stove, the cabinet door needs to be provided with ventilation holes; Both the size and the stability of the pull wire operating mechanism directly affect the working reliability of the burner. [0003] Some of the existing upward air-intake burners generally have small ejectors, which cannot meet the large-load ejection requirements, so the heat load is generally small, only ab...

AI Technical Summary

Problems solved by technology

[0003] Some of the existing upward air-intake burners generally have small ejectors, which cannot meet the large-load ejection requirements, so the heat load is generally small, only about 3.5-4.0kW, and the combustion flame is small, which cannot reach Chinese food. stir fry demand

At the same time, because the injector is small, the adaptability to gas is poor, and the combustion stability is poor, so it has not been well promoted.

[0004] There is airflow interference between the primary air and the secondary air when some existing complete upward air intake burners are working, frequent air grabbing occurs, and poor combustion stability
