The larger fuel flexibility of 30 ton circulating fluidized bed boiler for sale is applicable for the clients need various choices, which can use biomass, various kinds of coal include bituminous, anthracite, coke coal, lean coal .

The main benefits of 30 ton circulating fluidized bed boiler for sale

1.Large adaptability of fuel: this is one main advantage of circulating fluidized bed boiler. If calculated by weight inside the CFB boiler, the fuel is only 1~3% of bed materials, other materials are incombustible solid particles, like desulfurizer, ash, etc.

2.High combustion efficiency: CFB boiler has higher combustion efficiency than bubbling fluidized bed boiler, which can achieve 95~99%, it is because of the following features of CFB boiler: good effect of air-solid mixture, high burning rate and recycled combustion of fly ash.

3.High efficiency desulfuration:Due to the circulating combustion process, the limestone without desulfurization reaction inside combustion chamber are returned to bed materials, the part with desulfurization reaction produce large quantity of calcium sulfate, and collide, burst during recycling combustion process, the surface of new calcium oxide particles expose in atmosphere of vulcanization reaction, this will highly improve the performance of desulfuration.

According to some estimates global consumption of coal in 2030 is projected to be on the same as today. Coal consumption is increasing strongly in China, India and South-East Asia.In Europe coal consumption is estimated to never grow but nevertheless about 170GW of latest power generation capacity depending on non-renewable fuels must be installed by 2020. Ladies growing interest towards firing petroleum coke and other refinery byproducts to provide steam with high efficiency and availability in CFB boilers. Efficiency and environmental performance, especially CO2 emissions will be among the key issues to consider when planning the modern capacity.

The proven high efficiency circulating fluidized-bed (CFB) technology offers good solutions for high efficiency electricity production and CO2 reduction. Foster Wheeler will be the world’s leading supplier of high-efficiency, low-emission circulating fluidized bed (CFB) boilers for coal and petroleum coke firing. First high efficiency CFB power plants to work with the supercritical steam parameters in coal firing with once-though steam cycle technology are large.

Circulating fluidized bed (CFB) boiler technology has established its position being a utility-scale boiler technology. When contemplating either new plants or repowering old plants, efficiency and environmental performance include the key issues. High efficiency means lower fuel consumption, and lower stages of ash and air emissions, including lower emissions of skin tightening and (CO2). To realize these goals, supercritical steam parameters are actually applied.

Waste Heat Recovery Boiler is a system which recovers various kinds of waste heat generated from the production process of steel, non-ferrous metal, chemical, cement etc and those equipment of industrial furnaces, refuse incinerators, industrial waste incinerators, and convert such recovered heat into useful and effective thermal energy.Waste Heat Recovery Boiler is contributing to industrial society in terms of improvement of thermal efficiency, energy saving, environmental protection etc.

Conditions of the origin of waste heat depend upon each kind of facility which discharges waste heat. Conditions like gas temperature, pressure, corrosiveness, dust content etc vary depending on the conditions of each case. Therefore, deign and fabrication of waste heat recovery boiler require rich experience and technical capability. ZG is able to provide waste heat recovery boilers suitable to extremely tough conditions such as gas temperature of 1,500 degree C (2732 F) dust content of 400g/Nm3 (174 gr/dscf) and SOx content 40%. ZG has delivered more than 500 units of various kinds of waste heat recovery boiler, of which quality and reliability are highly reputed by the customers.

Climbing oil prices and growing demands for cleaner energy sources inspired many industrial boiler manufacturers to put a brand new spin on the traditional utilization of biomass to get steam as well as heat. Today’s biomass fired boiler integrates technology advances to build up automatic systems that manage accomplishing this from emissions and air control to ash removal. Using the modernization of steam boilers came numerous varieties, sizes and manufacturers, each one presenting new designs, cutting-edge technology.

The layout of a ZG boiler system includes three sections: a metering bin, a furnace as well as a ZG boiler that together to provide steam which they can use for heating or generating power within a steam turbine. Manufacturers make use of a number of ways to com-bust biomass feed-stock. The ZG system uses reciprocating fire grates to move feed stock over the boiler. Designed for use in large industrial settings such as factories, schools and greenhouses, it makes 3,450 to 10,000 pounds of steam per hour at 100 to 400 psi using biomass that has a moisture content of 30 to half.

ZG biomass fired Boilers available for purchase

The biomass fired boiler available for sale includes water tube and fire tube sections, which are insulated with 2 inches of mineral wool and engrossed in sheet steel lagging. It is this coating that keeps the boiler from reaching temperatures of 120 F. The initial 1 / 2 the hybrid boiler, the stream tube section, receives your initial heat from your burning fuel below. The water section is gas tight and composed of arched water tubes to produce heated water with the fire tube section.

The burning gases leave the lake tube and travel through horizontal pipes inside fire tube. Each tube is encompassed by water, and evaporates as the heated gas travels and doubles back with the tubes. On the fire tube section, steam travels through the top to be used as heat in buildings, or power steam generators. At this stage, any heavy particulates, or fly ash, are dropped in to a blower system that deposits them into the ash collector. The rest of the exhaust gas moves to the multicyclone collector.

Fluidized bed boilers
Fluidized bed boilers use the principle of burning fuels in a fluidized bed. A fluidized bed creates conditions suitable for the uniform combustion of fuel throughout its volume, which means, as a final result, more perfect fuel burn-up (high efficiency of a fluidized bed boiler) at lower combustion temperatures and whilst reducing the production of harmful waste gases at the same time.

Waste gases produced during fluidized bed combustion contain a significantly smaller percent of sulphur and nitrogen oxide contents compared to conventional combustion.

The principles of fuel burning in a fluidized bed also provide suitable conditions for burning a wide range of fuels such as coal, biomass, sewage treatment plant sludge, separated municipal waste, and others. The biomass fired fluidized bed boiler technology is thus the most perfect method of burning fuels both from an ecological point of view and an economical point of view, i.e. with the highest efficiency and the lowest emissions.
