Natural gas is a high-quality and efficient clean energy, carbon dioxide and nitrogen oxide emissions are only half and one-fifth of coal, sulfur dioxide emissions are almost zero. It is widely used in power generation, heating and industrial production. Compared with traditional fossil energy, natural gas has better environmental performance. 
 

	The gas infrared radiation heating method is to use the combustion of clean energy such as natural gas and liquefied petroleum gas to radiate infrared rays for heating. Infrared rays are not absorbed by the atmosphere, and the heating object is directly radiated, and the heating object absorbs infrared rays and is converted into heat energy, so as to achieve the purpose of heating. According to GB50019-2015 Design Code for heating, Ventilation and air conditioning of industrial buildings 5.5.4: When gas infrared radiation heating is used, the calculated indoor temperature should be 2℃ ~ 3℃ lower than the air temperature in the convective heating room, which reduces the air stratification and convective effect, and the heating system has a higher utilization rate of heat energy and reduces energy consumption.

IMPRESIND gas radiant heating system is promoted and sold by Beijing Leadway Power Co., LTD. The independent heater is installed in the upper part of the building heating space, which does not occupy the building space. Radiant heat directly radiates downward, the ground can also store part of the heat, indoor air temperature gradient is small, small heat loss, reduce heat consumption under the premise of ensuring comfort, to achieve the purpose of energy saving. 
 

	The thermal energy generator burns natural gas, and the hot fluid generated flows in the radiation tube under the drive of the negative pressure centrifugal fan. The gray and black radiation tube made of aluminum alloy and steel is excited by the high temperature surface to produce far infrared radiation, which directly acts the radiant heat on the objects and human bodies in the heating area. After the heat exchange of the hot fluid inside the radiation tube is finished, part of the product will be used for flue gas recirculation through the premix chamber, greatly improving the heating efficiency and making full use of energy. And the other part is directly discharged to the outside. Two heating to achieve the purpose of energy saving, environmental protection, reduce operating costs, comprehensive energy saving up to 30%~50%.

A perfect heating system must have intelligent software to cooperate with it. Such as intelligent control, remote control, can greatly improve the control accuracy and operational safety, reduce the loss caused by operational errors, and optimize the application design, the implementation of energy saving and emission reduction, reduce operating costs. 
 
The control system can realize independent control or centralized remote control. The smart LCD central control box can control up to 59 groups of devices and can be connected to a computer. The screen displays the usage and related parameters of each device. Automatic control and temperature regulation are convenient and can realize partition control temperature. According to the needs of users, the temperature of different periods of 24 hours can be set, which can be used for global heating and local heating, and the temperature of different periods of 24 hours can be set at 5℃ on duty heating temperature, and there is no need to design special on duty heating. At the same time, it has the function of automatic opening and closing on time, the equipment automatically stops when the ignition is unsuccessful, and restarts after the microcomputer detects the air source, power supply, negative pressure value and other safety protection devices are normal. 
 
At present, IMPRESIND gas radiation heating system has been successfully applied to Beijing Daxing International Airport China Southern Airlines A380 aircraft maintenance base heating project, Urumqi Diwopu International Airport cargo area heating renovation project, FAW-Volkswagen Tianjin factory heating project.
