In industrial manufacturing, industrial plant is one of the indispensable places in the production process, in order to ensure the winter production efficiency, heating is the key link, heating related costs are an important component of the production and operating costs of related enterprises. As people pay more and more attention to energy issues and environmental protection issues, how to achieve energy conservation and emission reduction of industrial heating has become one of the core issues that enterprises focus on. Especially in the heating of tall space industrial plants, energy saving is a necessary condition for sustainable development. 
 
At present, most of the domestic industrial plants still use the traditional heating method, the use of heat sources such as hot water boilers, steam boilers through pipelines and air handling units, heaters, radiators and other cooling equipment to heat the air in the plant, relying on air convection to achieve heating purposes. However, in the traditional convective heating system, due to the rise of hot air, a large amount of heat is consumed in the upper part of the tall building, and the lower working area is difficult to obtain enough heat, and the temperature distribution is uneven, which not only causes energy waste, but also poor thermal comfort. 
 
In the process of radiation heating, the heat is mainly concentrated in the middle and lower part of the room, which is more conducive to absorption and utilization by the human body. Therefore, radiation heating can better reduce the influence of temperature gradient than the previous two traditional heating methods. Compared with the traditional convection heating method, infrared radiation heating method has the advantages of fast heating speed, uniform heating, high thermal efficiency, high efficiency and energy saving. The heat conversion rate of infrared radiation heating is basically more than 90%, and the energy efficiency is higher. In general, the traditional convection heating method preheating time is 2 hours, the process of energy waste is huge; The infrared radiation heating equipment will have a warm feeling in a few minutes after opening, and the required indoor temperature will be reached in about 30 minutes. 
 
When the indoor air temperature is the same, radiant heat directly transfers heat to the heating object. The realistic temperature of radiant heating is 2~3℃ higher than that of convective heating. That is to say, under the condition that the indoor realistic temperature is the same, the indoor air temperature of radiant heating is 2~3℃ lower than that of heating, so the indoor heat consumption is small and the temperature difference between indoor and outdoor is small. The cold air permeability is also small, thus improving the indoor heating effect. The experiments show that the room temperature of 16℃ under the radiant heat condition is equivalent to the convection environment of 18~20℃. It is understood that if the room temperature is reduced by 1 ° C, about 10% of energy can be saved. 
 

	Beijing Leadway Power Co., Ltd. is a high-tech enterprise specializing in the development and sales of infrared radiation heating products and providing industrial heating solutions and services. The company is headquartered in Beijing. Now has "IMPRESIND gas radiation heating system" and "ECOPAN hot water radiation panel" two major radiation heating product brands.

 
1) IMPRESIND gas radiation heating system 
IMPRESIND gas radiant heating system is an independent heating system, consisting of three parts: generator, radiant tube and intelligent temperature control system. The generator burns natural gas, and the hot fluid generated flows in the radiation tube made of aluminum alloy and steel under the drive of the negative pressure centrifugal fan, producing infrared rays, and directly acting the radiant heat on the objects and human bodies in the heating area. 
 
2) ECOPAN hot water radiation panel 
ECOPAN hot water radiation plate is made of metal tube plate, with hot water as the heat conduction medium, flowing in the pipeline of the radiation plate, heat transfer to the radiation plate, generate infrared radiation, and directly act on the object and the human body in the heating area. The surface of the metal sheet tube is more than 280°, which increases the heat transfer area without long preheating time, and the heating speed is fast and uniform.
