For tall space heating, convection heating method not only consumes energy, but also difficult to solve the heating problem of tall space and other occasions, or the heating effect can not meet the ideal requirements. In contrast, infrared radiation heating is more suitable for tall space, large ventilation, local heating, gap heating and other tall space places, and its economy is very significant. It is used in a wide range of places, including large shipyards, maintenance halls for ships, aircraft and automobiles, building materials markets, shopping malls, exhibition halls, multi-functional stadiums and entertainment halls. 
 
Practice has proved that in the heating of tall space, infrared radiation heating has certain advantages in technology and economy compared with traditional water heating and steam heating (natural convection heating) and air heater (forced convection heating). Compared with traditional convective heating, infrared radiation heating has lower heat loss in tall space buildings. This is because when radiant heating, radiant heat directly irradiates the heating object, hardly heating the air in the environment, so the air temperature of radiant heating is lower than the air temperature of convective heating under the same health conditions, and can generally be lower by 2-3℃, so the indoor and outdoor temperature difference is small, so the building heat loss is also small. Because of the small temperature difference between indoor and outdoor during radiation heating, the cold air permeability is also small. 
 

	Due to convective heating, indoor air is heated, and the formation of hot and cold air convection, so the indoor air temperature has a large gradient, the roof part of the temperature is high, the temperature near the ground is low, the general convective heating temperature gradient is about 0.5-1.0oC/ m, and radiant heating, radiant heat directly downward radiation, the ground part can also save some heat, Therefore, the indoor air temperature gradient is small, which can greatly reduce the heat loss in the upper part of the house. At the same time, when infrared radiation heating, the thermal radiation temperature is higher, the human body and equipment receive more radiant heat, the temperature rise is faster, and the thermal comfort is strong, so it is recommended to use in tall space buildings. Since infrared radiation heating directly acts on the equipment or the human body, it is not necessary to heat the air first, and it can be oriented heating or local heating in tall space buildings.

IMPRESIND gas radiation heating system promoted and sold by Beijing Leadway Power&nbsp;Co., Ltd. is an independent heating system, which uses natural gas to burn in the generator to produce high temperature flue gas, the generated flue gas flows in the negative pressure radiation tube, so that the surface temperature of the radiation tube rises by 260-280 ° C, and the high temperature surface of the radiation tube generates infrared radiation waves to heat indoor objects. After the heat exchange of the flue gas inside the radiation tube is completed, part of the product will be used for recirculation heating, and the other part will be discharged outdoors. Its high efficiency of energy utilization makes it an obvious economic choice for industrial heating in large space. Compared with the traditional convection heating method, the gas radiation heating system not only reduces energy consumption, but also reduces energy costs, and saves operating costs for enterprises.
