Abstract

The invention relates to an air-temperature-type air supply device for a marine natural gas engine. The device comprises a liquefied natural gas steel bottle, a low-temperature valve, an air-temperature-type gasifier, a front pressure-regulating pressure gauge, a front pressure-regulating valve, a pressure regulator, a rear pressure-regulating valve, a rear pressure-regulating pressure gauge and a natural gas engine which are connected in series through pipelines; and an LNG (liquefied natural gas) steel bottle, the air-temperature-type gasifier and the natural gas engine are respectively fixed on a splint of a ship. The device disclosed by the invention has the advantages of simple structure, low cost, energy saving, safety and reliability in operation and carbon emission reduction, and is especially suitable for a marine power system in inland river basins in China.

Description

(1) Technical field [0001] The invention relates to a gas supply device for a marine natural gas engine, in particular to an air temperature type gas supply device for a marine natural gas engine. (2) Background technology [0002] At present, my country's marine power system mainly uses diesel as the power source. Diesel has been a shortage of fuel in my country in recent years. Using diesel as the energy source of the marine power system can neither adapt to my country's economic development situation, especially when the supply of diesel is becoming increasingly tense and the demand In the case of a rapid increase, it will inevitably cause the price of diesel to rise continuously and the operating cost to continue to increase. More importantly, it cannot meet the energy-saving and emission-reduction requirements proposed by the state. my country's inland waters are vast, and there are a large number of small and medium-sized ships operating in the inland waters. In this ca...
