CFB Biomass Fired Boiler For Sale

 In the combustion system of CFB boiler, the feeder feeds the biomass fuel into the furnace, and the air needed for the combustion of the boiler is provided by the primary and secondary fans respectively. The air sent out by the primary fan is preheated by the primary air preheater and is introduced into the cooling air chamber of the furnace by the air ducts on both sides, and enters the combustion chamber through the hood on the water cooling air plate. After the air from the secondary fan is preheated by the secondary air preheater, it is sprayed into the furnace through the nozzles distributed on the front and rear walls of the furnace to supplement the air and strengthen the disturbance and mixing.



CFB biomass fired boiler fuel and air in the furnace fluidized state mixing combustion, and heat exchange with the heating surface. The flue gas in the furnace (which carries a large number of unburned carbon particles) is further heated by combustion at the upper part of the furnace. After the flue gas leaving the furnace and entrusting a large number of materials passes through the volute cyclone separator, most of the materials are separated out and returned to the furnace through the returner to realize circulating combustion. The separated flue gas is discharged through the steering chamber, high temperature superheater, low temperature superheater, economizer, primary and secondary air preheater by the tail flue.

This series of industrial boiler products because of the use of circulating fluidized bed combustion, by adding limestone to the furnace, can significantly reduce the emission of S02 in the flue gas, the use of low temperature and air grading for wind combustion technology can significantly inhibit the generation of NOx. Its ash slag has good activity and high comprehensive utilization value, so it can be more suitable for increasingly strict environmental protection requirements.

Circulating fluidized bed boiler structure is single cylinder horizontal type, "Ï€" type arrangement. The membrane water-cooled wall is suspended in the furnace and the inlet of the separator is the membrane water-cooled flue. Adopt bell hood with easy replacement, low resistance and no dust pouring. The separator and the center barrel are improved with low resistance and high separation efficiency. Adopting the patented reverse material device and equipped with an independent fan for air supply, saving power consumption. Adopt low bed pressure operation mode.



The boiler series adopts primary fan with lower pressure head to reduce the power consumption of the fan. Optimized secondary air layout and nozzle flow rate, reduce the pressure head of secondary fan. The air preheater adopts multi-tube box arrangement, and the low temperature section adopts corrosion resistant steel pipe, which avoids the overall replacement caused by low temperature corrosion. Zozen Boilers specialize in producing all kinds of boiler products, welcome customers to our factory to consult and purchase.

Parameters and technical requirements of 6-ton gas-fired steam boiler for hospital use

 The 6ton gas-fired steam boiler is commonly used in hospitals, and its process requirements are as follows: Natural gas boiler: natural gas → burner → boiler → steam → sub-cylinder → steam point. Tap water constant pressure water supply → water softener → soft water insulation water tank → energy saver → boiler. Hospitals are densely populated places, so the requirements for boiler equipment and suppliers are relatively strict. Suppliers of 6ton gas boilers must have a Class A boiler manufacturing license, a pressure vessel manufacturing license, a Class 2 boiler installation, renovation and maintenance license or above. The equipment supplier shall be responsible for obtaining relevant certificates and fees such as the registration certificate for installation and use of boiler equipment. The water supply of this series of gas boilers is designed with a flue gas condensation recovery device to recover the heat energy of the flue gas, and the exhaust gas temperature is less than...

SZS Gas-Fired Horizontal Water-Tube Saturated Steam Boiler

 The pipelines within the scope of the SZS watertube steam boiler only include the valves and pipelines from the flange of the return water check valve to the outlet valve and drain valve of the boiler body. Accessories include valves and gauges for the boiler body. Such as pressure gauges, air valves, spring safety valves, outlet and return valves, check valves, thermometers, etc. The SZS gas-fired steam boiler is equipped with a flue gas condenser at the tail of the boiler body, which reduces the flue gas temperature (<70°C), improves the boiler efficiency and reduces the harmful components in the flue gas. The boiler adopts micro-positive pressure combustion, and the furnace wall tube is a full-membrane wall structure. This series of boiler products has a certain pressure bearing capacity, and no smoke leakage and air leakage will occur when running under a slightly positive pressure state. The boiler is a self-contained boiler, which can shorten the installation period whi...

35 Tons SZS Gas Steam Boiler

 The SZS gas fired steam boiler is equipped with a flue gas condenser at the tail of the boiler body, which reduces the temperature of the flue gas, improves the efficiency of the boiler, and reduces the harmful components in the flue gas. The szs gas boiler adopts micro-positive pressure combustion, and the furnace wall tube is a full-membrane wall structure. The 35ton gas-fired boiler has a certain pressure-bearing capacity, and there will be no smoke leakage and air leakage when running under a slightly positive pressure state. The boiler is a self-contained boiler, which can shorten the installation period while meeting the transportation size requirements. At the same time, the aluminum casing and the skeleton are transported and connected by bolts, which are convenient for disassembly and maintenance. The furnace of this series of boiler products adopts a model water-cooled wall structure, and the whole boiler adopts an air-tight inner shield with a fully enclosed welding s...
