Main types and applications of boilers

Boilers, important thermal energy conversion equipment, exhibit diverse types and wide application scenarios in practical applications. Their main types and application scenarios are as follows:

From the perspective of the medium, boilers can be divided into steam boilers, hot water boilers, and organic heat carrier boilers. Steam boilers are mainly used for steam generation, with water vapor as the output working fluid, widely used in power plants, ships, locomotives, and industrial and mining enterprises. Hot water boilers are mainly used for hot water production, with unsaturated hot water as the output working fluid, mostly used for residential hot water supply and auxiliary heating in industrial production. Organic heat carrier boilers can meet the special needs of low-pressure and high-temperature heat energy, often used in specific industrial fields.

According to fuel classification, boilers include coal-fired boilers, oil-fired boilers, gas-fired boilers, waste heat boilers, electric heating boilers, and biomass boilers. Coal-fired boilers use coal as fuel and have a long history; oil-fired and gas-fired boilers use oil and gas as fuel respectively, with better environmental performance; waste heat boilers utilize industrial waste heat, with significant energy-saving effects; electric heating boilers convert electrical energy into thermal energy, flexible and convenient; biomass boilers use agricultural waste as fuel, environmentally friendly and renewable.

In addition, according to their use, boilers can also be divided into power plant boilers, industrial boilers, and domestic boilers. Power plant boilers are mainly used for power generation, with large capacity, high parameters, and high efficiency; industrial boilers are widely used in textile, food, clothing, and other industrial production fields, providing steam to assist production; domestic boilers serve daily residents' water and heating needs.

In summary, boilers have diverse types and wide application scenarios, providing indispensable thermal energy support for industrial production and residents' lives.
