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.

Feed Water System - marineengineering.

Shown above is a typical feed water system for a modern steam plant. Water is pumped from the main condenser by special centrifugal pumps (Supercavitating) having an inducer to allow suction from the very low pressures without vaporisation of the water.

Efficient Water Heating Options | Home Powe

You can use a 50' long coil of 1/2; or 3/4; copper tubing, and a standard solar hot water heating controller. Only difference is the controller will sense the hot coil of tubing at night, when the stove is lit, and turn on the pump then.
