Problems solved by technology
[0004] The traditional dry process production line uses coal-fired boiler heat transfer oil to supply heat inside the oven. If natural gas direct combustion technology is used to complete the heat supply inside the oven, there will be problems, because all combustion heat transfer processes of natural gas combustion devices It will produce flammable and explosive gas, which will fill the oven, and once the concentration and temperature reach a certain level, it will cause fire or even explosion, which poses a serious safety threat

Description
technical field [0001] The invention belongs to the field of accessories for a synthetic leather dry-process production line, in particular to a natural gas direct-fired heating device for a synthetic leather dry-process production line. Background technique [0002] Synthetic leather production (including dry process and wet process) requires a lot of heat energy. At present, the heating equipment of most synthetic leather enterprises in my country is heated by coal-fired boilers. In the actual use and operation of coal-fired boilers, the thermal efficiency is low, the energy waste is large, the dust concentration is high, the sulfur content of coal is high, and the air pollution is serious. Especially in recent years, the contradiction between energy supply and demand and environmental pollution has become increasingly prominent. [0003] Natural gas direct combustion has high heating efficiency, low air pollution, and good environmental protection performance. Natural g...
