What is a shell boiler?

Shell boiler is what we usually call fire tube boiler. The boiler has a double jacket structure. The outermost outer cylinder is called shell, and the inner cylinder is called furnace lining. Medium water is the space between the outer cylinder and the inner cylinder, and the inner cylinder is the combustion chamber. The smoke flame passes through the inner cylinder. When pressure is generated during boiler operation, the shell bears internal pressure and the furnace liner bears external pressure.

1, the boiler is a kind of energy conversion equipment. The energy input to the boiler includes chemical energy and electric energy in fuel, and the boiler outputs steam, high temperature water or organic heat carrier with certain heat energy. The original meaning of a pot refers to a container for holding water heated on a fire, and a furnace refers to a place where fuel burns. A boiler consists of two parts: a pot and a stove.

2. The hot water or steam generated in the boiler can directly provide the required heat energy for industrial production and people's life, and can also be converted into mechanical energy by steam power devices or converted into electrical energy by generators. Boilers that provide hot water are called hot water boilers, which are mainly used in life and have a small number of applications in industrial production. Boilers that generate steam are called steam boilers, usually referred to as boilers for short, and are mostly used in thermal power plants, ships, locomotives and industrial and mining enterprises.
