DHX Type Circulating Fluidized Bed Boiler For Central Heating

DHX type circulating fluidized bed boiler is a product that ZOZEN'S has improved and improved on the basis of absorbing the advantages of circulating fluidized bed boilers at home and abroad. Through measures such as reducing the cycle rate and optimizing the structure of key parts, the problems of boiler wear, coking and clogging of the return device, high original dust concentration of the boiler, and difficulty in slag discharge have been effectively solved. The structure of the boiler is more reasonable, the performance is better, and the operation is safer and more reliable.

Based on the energy-saving circulating fluidized bed combustion technology of fluid state reconstruction, the DHX circulating fluidized bed boiler overcomes the two problems of high power consumption and wear and tear of the conventional circulating fluidized bed boiler in one fell swoop. The power consumption of the plant can be reduced by at least 30%. At the same time, the reduction of boiler wear makes the boiler availability rate increase, and the maintenance cost is correspondingly reduced.

Due to the violent mass and heat exchange in the fluidized bed, unburned coal particles can increase their residence time in the furnace through multiple cycles, which is very conducive to fuel burnout. DHX type CFB boiler can not only burn bituminous coal, lignite and other flammable coals, but also anthracite and other non-combustible coals. The waste slag can be used comprehensively. The carbon content of the slag is generally below 2%, and it can also burn bark and garbage. And other biomass fuels.

The circulating fluidized bed boiler can obtain a desulfurization rate as high as 80%-90% under the appropriate calcium-sulfur ratio and limestone particle size. This series of boilers product have sufficient output, sufficient and reasonable surface layout, and rapid heating and pressure rise of the boiler. The load adjustment range is large, and it can run stably under 30-110% load. Good anti-wear performance The furnace adopts special anti-wear materials and construction.

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...
