Our oil/gas fired boilers can be divided into SZS water tube boilers and WNS fire tube boilers depending on the medium inside the tubes. With multiple pressure designs, the water tube boilers can meet the steam supply requirements of 2.5MPa or above.

Our coal-fired chain grate boilers and coal-fired fluidized bed boilers mainly produce hot water, saturated steam or superheated steam for industrial use. Coal-fired boilers have lower operating costs – nearly 50% lower than boilers using oil or natural gas.

We cooperate with Shanghai Jiao Tong University to research, develop and manufacture biomass boilers that use wood chips, straws, palm shells, mesocarp fiber, empty fruit bunch (EFB) fiber, rice husk and other wastes as fuels in order to achieve zero carbon dioxide emissions.

Our product range includes biomass fired thermal fluid heaters, coal fired hot oil boilers, oil/gas fired thermal fluid heaters and molten salt heaters. We also offer thermal fluid heaters systems and solutions.

7*24 hours of counseling service, offering the most effective and fastest service to ensure that the loss caused by the failure for customers is minimized.

Steam locomotive - Wikiped

A steam locomotive is a type of railway locomotive that produces its pulling power through a steam engine. These locomotives are fueled by burning combustible material – usually coal, wood, or oil – to produce steam in a boiler. The steam moves reciprocating pistons which are mechanically connected to the locomotive's main wheels (drivers

Boiler Controls And Thermostats - Whic

Top tips for using boiler controls and thermostats Room thermostats. A room thermostat works by sensing the air temperature in the room. It switches on the heating when this falls below the thermostat setting, and switches it off when the required temperature is reached.

Steam engine - Wikiped

A steam engine is a heat engine that performs mechanical work using steam as its working fluid.In simple terms, the steam engine uses the expansion principle of chemistry, where heat applied to water evaporates the water into steam, and the force generated pushes a piston back and forth inside a cylinder. This pushing force is typically transformed, by way of a connecting rod and flywheel
