Gas infrared radiation heating system refers to the use of natural gas, liquefied petroleum gas, gas and other combustible gases, through a specific combustion, radiation device to generate a certain wavelength of infrared, and the use of this infrared transmission for heat transfer to achieve heating, the use of this method has the advantages of reducing the heat transfer link, high efficiency, uniform temperature distribution, comfortable.And can achieve fixed temperature, timing automatic control, energy saving effect is also quite obvious.Especially in the tall space, gas infrared radiation heating system has more advantages than convection heating.

	Compared with ordinary buildings, tall space buildings have the following characteristics: large span, tall layer, large door and window area and large heat transfer coefficient of envelope structure.Due to the large temperature gradient in tall space buildings, serious air stratification will result in greater heat dissipation on the roof.The use of gas radiation heating system in tall space, in addition to ensuring thermal comfort, can also make the heating interior design temperature than the traditional heating interior design temperature of 2 to 3 degrees.Thus, it can continuously create a good working environment, improve work efficiency, and energy saving and environmental protection.


	 


	At present, what are the safety requirements of gas infrared radiation heating systems?How should we protect it? 


	 


	According to the "heating ventilation and air conditioning design Code" (GB50019-2003) : "the installation height of the gas infrared radiator should be determined according to the comfort of the human body, but should not be less than 3m", the system is suitable for heating in tall space with a height higher than 4m, such as tall factories, car (machine) warehouses, tall exhibition halls, halls, gymnasiums and other places.For industrial plants, the rationality of the program should be discussed according to the specific conditions of the production process.For example, in the production process, a large amount of dust, fiber, volatile, flammable, corrosive gas (fog) and other workshop space is not suitable for gas radiation heating system.


	 


	Gas radiation heating equipment adopts negative pressure operation technology, the vacuum pump starts to work before the system ignition, and the controller confirms that the negative pressure is normal before ignition inspection.When any link of the system (power supply, gas supply, negative pressure, ignition) fails, the system will automatically shut down.The safety of equipment and heating area is fully guaranteed.


	 


	The gas radiation heating system promoted and sold by Beijing Leadway Power Co., Ltd. is controlled and monitored by an electronic device each time the fan is started for heating, to ensure that the pressure of the radiation circuit, the ignition situation, and the combustion state of the flame are correct, and the gas supply is cut off immediately in case of abnormalities and the equipment is locked.

	The radiation section consists of a series of modules 2 to 4 meters long, which are connected together by corresponding brackets.Each module consists of a black gray double-sided aluminum-impregnated steel radiation tube, and is connected with a special joint, which has special high temperature and flexibility, and is connected to the radiation tube section by a ring hook to maintain a fixed position.The solution does not use sealing compounds and compensates for the expansion caused by the heating of the modules, so that they do not cause dangerous expansion and stretching, and can be used for a long time.


	 


	Practice has proved that gas infrared radiation heating technology can well solve the problem of unreasonable temperature distribution in a large space, theoretically save energy 30% ~ 50% compared with convective heating, and can achieve room temperature and time-sharing, sub-regional control, and the economy is very obvious.Therefore, gas infrared radiation heating technology is very suitable for all kinds of railways, subways and civil plants, garages and other buildings with tall space.Gas infrared radiation heating system is suitable for high space building without explosive gas, dust place, good economic benefits.For remote places where there is no heat source but there is gas, compared with the new boiler room heating system, gas infrared radiation heating system is the ideal choice.
