The value is reduced to 1,000 psi. A second natural gas pressure reducer that reduces the natural gas pressure of 1,000 psi, the natural gas pressure value inherited from the gas reducer. Naturally, the number one reduced to 150 pounds per square inch. And a heat exchanger kit to help It does not allow natural gas to freeze when the natural gas is depressed by flowing through the damper. Pushes the first natural gas and flows through the second natural gas pressure reducer, which There is a hot water tank inside of which a hot water tank is equipped with a heating device for heating. To the water flowing into the hot water tank The hot water obtained from the hot water tank is stored in the water tank. The heat is supplied to the second natural gas pressure reducer and the natural gas pressure reducer at One in sequence, and then flows back to the hot water tank for further heating. Natural gas pressure reducing system with a set of natural gas receiving valves with inlet valve at One which will receive natural gas from natural gas transportation vehicles. The natural gas will flow along the natural gas pipeline, the first natural gas pressure reducer to reduce the natural gas pressure of 3,600 psi, which is the natural gas pressure received from the natural gas transport truck. The value is reduced to 1,000 psi. A second natural gas pressure reducer that reduces the natural gas pressure of 1,000 psi, the natural gas pressure value inherited from the gas reducer. Naturally, one has the value reduced to 150 psi. And a heat exchanger kit to help It does not allow natural gas to freeze when the natural gas is depressed by a flow through a damper. Pushes the first natural gas and flows through the second natural gas pressure reducer, which There is a hot water tank, which inside of the hot water tank is equipped with a heating device for heating. To the water flowing into the hot water tank The hot water obtained from the hot water tank is stored in the water tank. The heat is supplied to the second natural gas pressure reducer and the natural gas pressure reducer at One in order and then flows back to the hot water tank for further heating.
