sa fan for bagasse fired boilers

Walking in the village, we can see that the sparse crowd, in front of the elderly chat and play with the children. Economic tide makes the village more than half of young workers out of the countryside towards the city diverse work environment also means that the child grows missing parental care. Walk to campus, low school buildings, overcrowded classrooms, lack of basic education all reflect the hardware of the mountains. The onset of winter, the mountains to cool the most obvious. The children in the hands of the cold and muddy drinking water, people can not help but feel bad. These difficulties and shortcomings, becoming fast sa fan for bagasse fired boilers barbs lie in the hearts of all the staff, long linger in the mind.

Pressurization of water sa fan for bagasse fired boilers heating system for heating hot water heating system with a constant pressure common mode: constant pressure expansion tank, Common constant pressure supply pump, pressure tank, and the gas constant pressure, constant pressure steam, frequency control constant pressure supply pump, stable constant pressure water and other hydrating the constant pressure. Hybrid heater of the hot water system should be used in the form of overflow constant pressure. (1) the constant pressure expansion tank: In the embodiment above the highest point of the heating system 2-3 meters, provided a constant-pressure tank to maintain a constant pressure point is referred to as the constant pressure expansion tank. The advantage is that the pressure is stable afraid of power; disadvantage is the limited height of the tank, and when the higher maximum building floors away from heat, or high temperature hot water, the expansion tank erection height not meet the requirements. (2) Normal pressure up water pumps: heating system with a water supply pump continuously maintain a constant pressure point pressure of water filling method called fixed constant pressure supply pump. The advantage of this method is that simple equipment, less investment, easy to operate. The disadvantage is afraid of power outages and a waste of electricity. (3) a gas pressure tank, and constant pressure: nitrogen partial pressure of the given gas at constant pressure and two constant pressure air, is characterized by using a low-pressure tank, and the joint operation of water supply pump, the heating system to maintain a constant pressure. Constant pressure nitrogen is constant pressure filling nitrogen tanks. The constant-pressure air is filling the air, the air dissolved in water to prevent corrosion of pipelines, installed normally constant pressure in the air bladder tanks, the air and water separator. Constant pressure gas heating system advantages are: safe and reliable operation, can better protect the system and the vaporized water hammer phenomenon; disadvantages are: complex equipment, larger, more expensive, used for high temperature water systems. (4) Constant pressure steam: Steam is constant pressure by the pressure of the boiler drum vapor space ensured. For more than two boilers, may be employed externally constant pressure expansion tank vapor system. Further, the use of water spray produced by the present heater and the steam heater may be movable considered a constant steam pressure. Constant pressure steam advantages are: the system is simple, low investment and operational economics. The disadvantages are: constant pressure to steam pressure depends on the level of boiler combustion conditions, pressure fluctuations, if mismanagement steam fleeing into the water Netease cause water hammer. (5) Frequency constant pressure supply pump: The basic principle is to change the power frequency according to the pressure change in the heating system, smooth stepless adjustment of the supply pump and regulating the speed and fill water, constant pressure point for system pressure constant. The advantage of this method are: energy saving, easy to adjust the control pressure. The disadvantages are: large investment, fear of power outages. (6) a constant pressure water: tap water pressure during the heating system meet the heating value of the constant pressure and the pressure is stabilized. The water can be directly connected to the heating system return pipe, pay constant pressure. The advantage of this approach is apparent see, simple, minimal investment and operating costs; disadvantages are: narrow scope of application, and the quality is not directly heating process causes the heating system fouling. (7) forms the overflow constant pressure: constant pressure valve has a constant pressure, constant pressure and high water tank overflow pipe pressurization inverted U-shaped and the like. In operation, the highest point of the system is filled with water and there is inevitably a certain margin pressure head, and generally about 4m. Since the system is large floors for, and much smaller than the resistance of the return path for the resistance, and therefore, the runtime, the ram is higher than the highest point of the head rest. Thus, the value of the static pressure may be set appropriately lower, preferably generally 1 ~ 4m. Minimize pressure constant pressure value, in order to take full advantage of the ability to work in the steam.

The natural gas sa fan for bagasse fired boilers is located near the slaughterhouse as supplementary energy source for steam production. Its presence has three main reasons:

1.The heat demand of the slaughterhouse fluctuates on a short time scale. The natural gas boiler covers all rushing demands;

2. The heat demand varies seasonally, is generally higher in winter period due to lower ambient temperatures. In the period of higher heat demand the natural gas boiler ensures additional heat production;

3. The gasification and combustion plant needs regular maintenance breaks and is then unable to deliver any steam to the slaughterhouse.

The sa fan for bagasse fired boilers flue gas purification system

As environmental pollution intensifies, boiler equipment, which is a major source of pollution, continues to enhance its environmental performance. Boiler flue gas purification system including dust removal, desulfurization, denitration equipment, their role is to remove the boiler flue gas entrainment of solid particles (fly ash), sulfur dioxide, nitrogen oxides and other harmful substances, in order to improve the atmospheric environment.
