Gas radiant heating is one of the more popular heating methods for large Spaces at present. It is mainly used in large-scale industrial plants and public buildings, and it is energy-saving, environmentally friendly and comfortable. Gas radiant heating consumes less energy from the air, has a high energy utilization rate and a good heating effect. This is essentially different from the convective heating method. So, in the heating of large Spaces, how does gas radiant heating combine energy conservation, environmental protection and comfort? 
 
Energy conservation 
 
Gas radiant heating can save energy by up to 30-50% compared with convection heating, mainly reflected in the following aspects: 
 
Firstly, during radiant heating, the radiant heat directly irradiates the heating object and hardly heats the air in the environment. Therefore, the air temperature during radiant heating is lower than that during convective heating under the same hygiene conditions, generally by 2 to 5 degrees Celsius. As a result, the temperature difference between indoors and outdoors is small, and the amount of cold air infiltration is also relatively small. 
 
Secondly, during convective heating, the indoor air is heated and a convection between hot and cold air is formed. As a result, there is a significant temperature gradient in the indoor air, with the roof area having a higher temperature and the area near the ground having a lower temperature. Generally, the temperature gradient in convective heating is about 0.5 to 1.0℃ per meter. However, in radiant heating, the radiant heat radiates directly downward, and the ground area can also accumulate some heat. Therefore, the indoor air temperature gradient is small, and accordingly, the heat loss at the upper part of the building is also relatively small. 
 
Thirdly, there is no loss of gas during the transportation process, and at the same time, the combustion of the radiator is very complete. Therefore, the heat of the entire heating system is fully utilized. In contrast, in the traditional radiator heating system, after the heat source is drawn from the boiler, there is a heat loss of 10-15% along the way, so the thermal efficiency is relatively low. 
 
Fourth, there are fewer energy conversion links. 
 
2. Environmental protection 
 
Natural gas and liquefied petroleum gas are clean energy sources. Their combustion products contain no sulfides or dust, and they have high thermal efficiency, with a unit heat output of 8,000 to 8,500 kcal /m 3. 
 
Reduce nitrogen oxide emissions by 50% 
 
Reduce carbon dioxide emissions by 60% 
 
Reduce sulfur dioxide and dust emissions by nearly 100% 
 
3. Comfort 
 
Infrared radiation heating is similar to the radiation from the sun to the Earth. Unlike radiator heating, the sun can heat the Earth's surface through the atmosphere and radiate heat to the Earth's surface. This is because the physical properties of the atmosphere are close to those of an ideal gas. When infrared rays pass through the air layer, there is very little attenuation and they are rarely absorbed by the air. Infrared rays can pass through the air layer to directly heat the radiated area. The radiated heat can be absorbed by concrete floors, people and various objects, and then undergo secondary radiation through these objects, thereby heating other objects around. 
 
IMPRESIND gas radiant heating system generator, promoted and sold by Beijing Leadway Power Co., LTD., burns natural gas. The resulting hot fluid flows in the radiant tubes made of aluminum alloy and steel under the drive of a negative pressure centrifugal fan, stimulating infrared rays and directly applying the radiant heat to the objects and human bodies in the heating area. After the heat exchange inside the radiant tube is completed, a portion of the products will pass through the premixing chamber and be used for flue gas recirculation, significantly enhancing the heating efficiency and fully utilizing energy. While the other part is directly discharged outdoors. The two heating processes can achieve the goals of energy conservation, environmental protection and cost reduction in operation. The comprehensive energy savings can reach 30% to 50%. IMPRESIND gas radiant heating system is particularly suitable for large space buildings. Due to its functions of local regulation and zoned temperature control, it has become one of the commonly used heating forms in large Spaces such as industrial plants, aircraft hangars, logistics centers, exhibition halls, and stadiums in China at present.
