The heating problem of tall space industrial plant in winter has always been a difficult problem in the industry. In the building space of industrial plants, there are widespread problems such as large heating area, high energy consumption and high operating costs. Therefore, in the choice of heating equipment, the following factors should be considered: energy saving, environmental protection and heating effect of the equipment. 
 
At present, according to the different nature of the use of buildings, the heating of general industrial plant buildings mainly adopts convection heating and radiation heating. 
 

	The traditional heating method of industrial plant is to use heat sources such as hot water boilers and steam boilers to heat the air in the plant through pipelines and air handling units, heaters, radiators and other cooling equipment, and rely 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.

The heat in the radiation heating process is mainly concentrated in the middle and lower part of the room, which is more conducive to being absorbed and utilized by the human body, the temperature rise is faster, the thermal comfort is strong, the energy consumed in the air is less, the energy utilization rate is high, and the heating effect is good. Therefore, compared with the previous two kinds of heating, radiation heating can better reduce the influence of temperature gradient, and achieve the heating effect that is difficult to achieve with convection heating. 
 

	Radiation heating is mainly obtained from the radiation source directly, and the indoor air temperature is always lower than the temperature of the surrounding object, which is also the reason for the energy saving of radiation heating. 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.

In recent years, with the diversification of heating forms, radiation heating has developed rapidly in our country, and almost all kinds of buildings such as industrial plants and large building facilities have examples of the application of radiation heating, and the use effect is mostly very ideal. Compared with the traditional convection heating method, the gas radiation heating system not only increases the user's use area, reduces the amount of maintenance, solves the problem of serious pollution, difficult maintenance, cold and hot inequality caused by the traditional heating method, not only applies to the overall temperature improvement of industrial plants, but also meets the special heating needs of local regional heating and intermittent heating in the internal space of the plants. 
 
IMPRESIND gas radiation heating system promoted and sold by Beijing Leadway Power&nbsp;Co., LTD., can be customized according to the actual situation of the plant heating system solutions, not only to achieve independent heating in different regions, switch, temperature, mode, etc., can also be flexibly regulated. Users according to real-time weather conditions, use needs, personalized setting of heating temperature, effectively improve the operating efficiency of the heating system, reduce energy consumption, comprehensive energy saving up to 30%~50%.
