Combustion device for natural gas pressure relief

The utility model relates to the technical field of combustion devices, in particular to a natural gas pressure relief combustion device which comprises a box body, a gas inlet pipe is connected to one side of the box body in a clamped mode, two acceleration blocks are connected to one side of the box body in a clamped mode, a fan is connected to one side of the box body in a rotating mode, and two deceleration blocks are connected to one side of the box body in a clamped mode. A combustion-supporting gas inlet pipe is connected to one side of the box body in a clamped mode. The utility model has the advantages that the natural gas enters the two acceleration blocks through the gas inlet pipe, the gas is divided into two parts by the two acceleration blocks, the natural gas can be accelerated because the gas inlet port of each acceleration block is large and the gas outlet port of each acceleration block is small, and the natural gas enters the middle part of the clamping groove of the box body in an accelera
