Discussion about Selection of Explosion-Proof Electrical Equipment for Inland LNGas Bunkering Pontoons
The promotion of inland liquefied natural gas(LNG)ships plays an important role in promoting the goal of china's peak carbon dioxide emissions,but LNG is flammable and explosive.If the explosion-proof electrical equipment is not properly selected,it may affect the normal filling operation and even lead to major safety accidents.For different dangerous areas,scientific selection of explosion-proof electrical equipment is of great significance to the safe operation of LNG filling in inland rivers.This paper expounds the explosion danger of inland LNG bunkering pontoons and the problems existing in the selection of electrical equipment,divides the explosion danger areas,and gives the selection principle,process and method of explosion-proof electrical equipment.Taking the explosion-proof projection lamp at the joint of the cargo tank of an inland LNG bunkering pontoons as an example,the selection of explosion-proof equipment is analyzed.It provides a reference for the construction design,explosion-proof electrical equipment selection and maintenance management of inland LNG bunkering pontoons.
