Description

Radiation heating system main unit and radiation heating system

Technical Field

The present application relates generally to heating technology, and more particularly, to a radiant heating system and a radiant heating system having more stable thermal efficiency.

Background

In general, gas radiation type heating is performed by burning a combustible gas such as natural gas, liquefied petroleum gas, or artificial gas in a special burner, i.e., a radiant tube, to radiate infrared rays of various wavelengths, which are a part of the entire electromagnetic wave band. Electromagnetic waves with different wavelengths will produce different effects when contacting an object. Electromagnetic waves with a wavelength between 0.76 and 1000 microns, especially between 0.76 and 40 microns, have non-dispersive properties, and thus, energy is concentrated and thermal effects are significant.

The gas radiation heater is generally composed of a burner, an igniter, a radiant tube, a draught fan, a control box, a reflecting cover and a safety device. The shape of the radiant tube is like a fluorescent lamp, the length of the radiant tube is from about 5m to more than ten meters according to different types, and the radiant tube can be used after being connected with an air source and a power supply.

Generally, the gas radiation heater does not need to worry about the problem of freezing, because the combustor just burns the machine in the host computer, but on the one hand, the requirement for energy saving and environmental protection is higher and higher now, and on the other hand, the combustor also does not burn continuously in the host computer, and under the condition that the temperature is lower in winter in the north, if the combustor stops for a long time in the host computer, parts such as a filter screen, a valve plate and the like of a gas system in the host computer of the gas radiation heater can easily produce condensate at low temperature because of impurities in natural gas, even block an air supply pipeline, and the main computer can not be started and operated normally. The existing method for eliminating the faults generally needs a manufacturer to preheat a host by using an external heat source manually before starting the computer, and then remove the external heat source after the computer is normally started. However, this method affects the customer experience on one hand and causes a large waste of cost on the other hand, and it is necessary to provide a technical solution to solve this technical problem.
