Industrial plant is one of the indispensable places in the production process, in order to ensure winter production efficiency, heating is the key link, especially in the heating of tall space industrial plant, energy saving is a necessary condition for sustainable development. The choice of heating equipment is very important for the high space industrial plant to achieve energy saving. 
 
The traditional convection heating heat transfer method is through the heat medium in the traditional heating equipment circulation, through the heat released by the traditional heating equipment heating the surrounding air, the air is heated up, the formation of air convection, which is a gradual and slow process, the space temperature gradient formed by it is hot and cold. 
 
Infrared radiation heating technology is to simulate the way the sun transfers heat. Radiant heating equipment transmits more than 95% of the heat downward in the form of infrared waves. When the ground, personnel, and objects below receive heat, they gradually dissipate heat into the air, forming a bottom-up heat flow and a low temperature gradient. 
 

	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. 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.

IMPRESIND gas infrared radiation system, promoted and sold by Beijing Leadway Power Co., LTD., is an independent heating system, consisting of three parts: generator, radiation 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. The indoor air temperature of gas radiation heating is 2 ~ 3℃ lower than that of convective heating, the indoor air temperature gradient is small, the heat loss is small, and the cold air permeability is also small, and the heat energy consumption is reduced under the premise of ensuring comfort to achieve the purpose of energy saving, which is the ideal heating equipment for tall space industrial plants. 
 
According to the Code for Fire Protection of Building Design: "The use of gas, liquid, solid as fuel or the combustion of gas, liquid for other purposes of various production" fire risk category belongs to Class D. Therefore, the use of gas radiation heating will not increase the risk and design difficulty of tall space buildings. The use of gas radiation heating system, as well as effective energy-saving measures, can ensure that the temperature inside the tall space industrial plant is comfortable, but also can reduce heating costs, increase the efficiency of enterprises.
