pulverized coal steam furnace

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.

Unique structural design

National Precision Bearing offers stainless steel for applications that require corrosion resistance.We have world class manufacuring facilities using latest technology, machines and equipments.

coal utilization | Volatile Matter ; Chemistr

Coal utilization, combustion of coal or its conversion into useful solid, gaseous, and liquid products. By far the most important use of coal is in combustion, mainly to provide heat to the boilers of electric power plants. Metallurgical coke is the major product of coal conversion. In addition, techniques for gasifying and liquefying coal into fuels or into feedstocks for the chemical

PULVERIZED COAL FURNACES - Thermoped

Pulverized coal (pulverized fuel-pf) has been fired in rotary cement kilns (see Kilns) and boiler furnaces (see Boilers).The latter are basically boxes lined with tubes in which water is evaporated and contain a water/steam mixture. The coal is pulverized to a fine powder, usually so that 70% is less than about 75 μm in size, before being carried by part of the combustion air stream to the

Non Coking Coal for Iron Production | ispatgu

Non Coking Coal for Iron Production. A non-coking coal is that coal which when heated in the absence of air leaves a coherent residue. This residue does not possess the physical and chemical properties of the coke and is not suitable for the manufacture of coke.

Pulverized coal-fired boiler - Wikiped

A pulverized coal-fired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal (also known as powdered coal or coal dust since it is as fine as face powder in cosmetic makeup) that is blown into the firebox.. The basic idea of a firing system using pulverised fuel is to use the whole volume of the furnace for the combustion of solid fuels.
