7 ton wood fired biomass boiler

The 7-ton wood chip biomass boiler is a common application in hotels, food processing plants, wood processing plants, and wood is a very common biomass fuel, but it is not suitable for direct use in boilers. In general, biomass such as wood needs to be processed into granules for better utilization. Wood biomass boilers mainly use wood pellets as fuel to generate steam or hot water for various purposes.

What a 60bhp biomass fired steam boiler performance was uneven heat? The following is a non-uniformity reasons: 1, non-uniform heat absorption of the steam boiler. Closely related to the arrangement, operation mode and the type of fuel causes nonuniform heat absorption of the burner. Uneven temperature distribution in the furnace, the heat causes a small load intensity of each furnace waterwall. In general, in the case where the same type of fuel, the heat load distribution in the furnace slagging liquid much larger than the heat load distribution in the furnace slagging solid. Fuel burner heat load is larger than the unevenness of the uneven heat load fired furnace, hot offset vertical tube panel screen than the horizontal tube thermal excursions. DC endothermic steam boiler unevenness different from the natural circulation steam boiler. Natural circulation steam boiler having a heat compensation characteristics, can play a major role in reducing thermal excursions, but the evaporator heating surface in direct steam boiler, heat absorption for larger tube, because the steam generation amount of the inner tube, large capacity . Increase the resistance, the flow rate of the steam pipe is reduced. Conversely, increasing the flow rate of weak heating pipes. Therefore, the DC steam boiler evaporator heating surface will not only cause non-uniform endothermic thermal excursions, but also to expand the non-uniform heat flow by influencing the deviation. 2. The flow rate of the steam boiler is not uniform. Electric heating boiler and the boiler is mainly composed of electric control box and control system. Its characteristics are environmentally friendly, clean, no pollution, no noise, automatic, with limited energy and reduce prices significantly, as a new boiler electric heating boiler equipment increasingly being recognized. Electric heating the core member is electrically heated boiler, directly determines the life of the boiler, to select a non-metallic electrical heating tube (such as a ceramic heating pipe), because it is resistant to the load, a long life, and a water separation structure, the boiler Wing no leakage. Biomass boiler is a kind of boiler to biomass energy as a boiler fuel called biomass boilers, steam boilers into biomass, biomass hot water boiler, biomass stove, biomass thermal oil heaters, vertical raw biomass boilers, biomass boilers and other horizontal. Different resistance to flow parallel to the tubes of the evaporator heating surface, and a change in pressure along the length of the header, and the difference in weight between the head tube and the tube will lead to non-uniform flow. Variation on the thermal flow resistance. Since the structure of the steam pipe, the quality, of different length, diameter, roughness and curvature, the flow resistance is different. Under the same pressure, the flow resistance can cause uneven. When the thermal head 2 in the high-pressure variation in the vertical riser screen, since the height of the larger screen, parallel tubes uneven heating, density vary greatly, it should consider the impact ram repositioning. When high heat load single tubes, the tube bundle of the flow decreases. However, due to the reduced density of the working fluid within the tube and the weight of the head is reduced, the flow rate increases. Accordingly, high pressure water is advantageous to reduce thermal excursions.

Since last year, the city of Yinchuan in Ningxia to develop clean energy alternative to coal heating work carried out, in order to adhere to the use of waste heat energy-based heating system, two years, a total removal of 212 coal-fired boiler units, designed over 20 million square heating area Meter. At present, Yinchuan City, the formation of a waste heat recovery and cogeneration-based, clean energy co-existence of a new pattern of heating, coal heating gradually withdraw from the stage of history.

According to Yinchuan City Housing Construction Bureau feedback, early last year, Yinchuan City, began to promote the implementation of "East of the West to give a" heat of long-distance heating projects, the long-distance transmission projects across the Yellow River, the basic realization of restructuring heat source, heat source interconnection point to ensure the city heating security and stability, environmental protection is of great significance.

At present, "East of the West to give a" central heating heating net charge of the project, the city branch, etc. have been completed, the east, the city water pipe network has been completed and started flushing cycle, is west of the water, water totaled 145,000 cubic meters.

At the same time, Yinchuan City, also build a heat source, thermoelectric Xixia complete the second phase of construction, the new 2 sets of 350,000 kilowatts supercritical coal-fired air-cooled heat generators, which can effectively replace Yinchuan City, 154 small coal-fired boilers, the annual generating capacity 3.85 billion kwh, heating capacity of 16.42 million square meters.

This year Yinchuan new cogeneration district heating area of ​​41 million square meters, the new heating pipe network 86 kilometers, is the largest investment project ever central heating, with the largest of the year.

The amount of coal to produce one ton coal-fired 60bhp biomass fired steam boiler steam consumption is about 150kg.

Second, biomass steam boiler
