ZOZEN's main products include industrial boilers, power station boilers, waste heat recovery devices (HRSG), special waste heat boilers, pressure vessels and other five series with more than 400 varieties of specifications, mainly classified as: 10 ~ 220 t/h series power station boilers; SHL series bulk coal-fired Steam and hot water boilers; SZL series pipe assembly boilers; DZL series shell boilers; WNS series, SZS series of oil/gas fired boilers; YLL series of coal-fired thermal fluid heater; YYW series of fuel gas thermal fluid heater; biomass fuel boiler steam and gas combined cycle waste heat boilers, special waste heat boilers and so on.


ZOZEN has built six fully automatic lines for the production of convection pipe, coil pipe, threaded pipe, membrane wall, serpentine tube and header. The parts so produced have consistent dimensions that enable easy assembly and ten years’ extension of a boiler’s life.

Our Lastest Boiler Type

Seven Hold Points

Seven hold points are set and each one is supervised by a responsible inspector. Any work that fails to pass the inspection cannot proceed until the inspector is able to verify its quality.

1,Incoming materials are inspected again upon entry into the plant.

2,Material markings will be transferred to all cut pieces to ensure identification and traceability.

3,Test pieces are used to ensure a higher success rate in welding.

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

Streamlined Ste

Out of the 120,000 or so steam locomotives built and used in the United States, only about 220 were streamlined–or, as the Chicago ; North Western called it, steamlined–for passenger service. Railroads went to the trouble to streamline steam locomotives for three reasons.

MHI Superheated Steam Generators One Atmospher

What is superheated steam? What is saturated steam? When water molecules exist in a gaseous-state at a temperature above the boiling temperature of water, it is called the superheated steam-state.When at the boiling-temperature, the steam is called saturated steam.

Steam World: January 2009

Steam World, popular magazine about steam locomotives. The Editors of this magazine, which does not set out to be profound, have been highly successful in capturing material both from professional locomotive engineers (who very sadly are a shrinking breed), from senior railway managers, and from people like Andrew Dow who enjoyed priviledged access to railways at an early age.
