Upper-air-intake dual-ring combustor

Abstract

The invention relates to an upper-air-intake dual-ring combustor which comprises a base, nozzles, a foundation seat and burner caps. The base is embedded on a panel and is internally provided with a fuel gas channel; the nozzles comprise a first nozzle and a second nozzle communicating with the fuel gas channel; the foundation seat is supported on the base and comprises an inner-ring seat body andan outer-ring seat body arranged on the periphery of the inner-ring seat body at an interval; the inner-ring seat body is provided with an inner injection pipe; the outer-ring seat body is provided with an outer injection pipe; the burner caps comprise an inner-ring burner cap and an outer-ring burner cap; the inner-ring burner cap covers the inner-ring seat body in a matching way; an inner-ringgas mixing chamber is formed between the inner-ring burner cap and the inner-ring seat body; the outer-ring burner cap covers the outer-ring seat body in a matching way; an outer-ring gas mixing chamber is formed between the outer-ring burner cap and the outer-ring seat body; a temperature sensing probe stretching out to the upper part of the inner-ring burner cap is arranged in the inner-ring seat body; and a check ring is arranged on the top face of the inner-ring burner cap in an upward extending way along the circumferential direction, and is located on the inner circumference of a fire hole of the inner-ring burner cap. According to the upper-air-intake dual-ring combustor, the influences of flame, smoke and the like on the temperature rise of the temperature sensing probe can be reduced, so that the temperature measurement accuracy and the service life of the temperature sensing probe are improved and prolonged.

AI Technical Summary

Benefits of technology

This new technology makes it possible for an indoor gas cooktop that uses this type of device to accurately measure temperatures without being affected from external factors like ambient light or other sources such as sunlight during operation.

Problems solved by technology

This patented technical solution described in this patents describes two types of current methods for improving the design of heat sources within electronic devices like furnaces or refrigerator cabinets. One method involves adding a separate component called a thermistor inside the fuel tank itself instead of directly measuring the temperature from outside. Another approach uses multiple rings of oven tubels instead of one per seam length. These solutions aimed at reducing thermal shock during operation while maintaining good coolant supply around the temperature sensitive element.
