    摘要: A pressure reducing system for fuel gas and a natural gas dewaxing vehicle are disclosed. The pressure reducing system (6) comprises fuel gas pipelines which consist of successively connected a high pressure pipeline (41), a medium pressure pipeline (42) and a low pressure pipeline (43) in the flow direction of fuel gas. The tail end of the low pressure pipeline (43) connects with an combustion apparatus (7). A high pressure relief valve (17), a high pressure air feed valve (21), a heat exchanger (24) and a primary pressure reducing valve subassembly are connected on the high pressure pipeline (41). The heat exchanger (24) is provided with a hot fluid inlet (24A) and a hot fluid outlet (24B), wherein the hot fluid inlet (24A) connects with an hot water apparatus (12), and the hot fluid outlet (24B) connects with an water storage apparatus. The medium pressure pipeline (42) is equipped with a medium pressure relief valve (27) and a secondary pressure reducing valve (29). The low pressure pipeline (43) is equipped with a low pressure relief valve (31) and a third pressure reducing valve (34). Because of the adoption of three-level pressure reduction, the pressure reducing system (6) for fuel gas can guarantee output pressure of natural gas meeting combustion requirements. The natural gas dewaxing vehicle comprises an automobile chassis (1), a bedplate (11), a water supply system, a dynamic system, a combustion mechanism, a gas storage device (9) and a pressure reducing system for fuel gas (6). The natural gas dewaxing vehicle, which employing the pressure reducing system (6) for fuel gas, can make it possible to use natural gas without enlarging the volume of a vehicle, and can largely reduce the cost of use and modification.
