5 tons coal fired steam boiler in vietnam

6 tons adjusting a combustion gas 5 tons coal fired steam boiler in vietnam, normal combustion boiler three basic aspects of indicators include a uniform supply of the fuel, reasonable ventilation, adjustment the combustion. 1, to maintain the high temperature of the combustion chamber temperature of the upper layer is preferably in the 1100 ~ 1300 ℃, flame orange in color. Flame reddish color indicates that the amount is not enough to the wind, the color white indicates that excessive wind. It should be appropriately adjusted. 2, fuel ash to reduce ash content in the combustibles to be below 10%. 3, reducing the temperature of the boiler flue gas exhaust gas temperature should be controlled below 200 ℃. 4, holding furnace negative excess air boiler is 1.2 to 1.4, by adjusting the balance of the blowers to maintain the furnace pressure is -20 ~ -30Pa. 5, the thermal efficiency of the boiler to improve the thermal efficiency of the boiler should be kept above 60%. II. Combustion Adjustment 1, the amount of fuel to air required for combustion and the amount of a reasonable distribution. Ventilation should first increase the amount of fuel increases, it should first reduce the amount of fuel supply reduced ventilation. 2, the thickness of the seam and seam thickness configuration grate speed is 80 ~ 120mm grate speed at high, middle and low profile configuration of several commonly used methods:. 9a rapid combustion of thin seam b c thick seam in low combustion. 3 thick seam combustion speed, the segment with the wind blowing principle: burn promoting intermediate ends. That is, after the coal into the coal starts to warm up the shutter, fire line front arch, the primary combustion zone, the middle grate to burn the rear grate zone. Normal combustion conditions are: fuel from the coal at the beginning of the fire shutter 300mm, uniform flames, the fire bed formation, at the end of combustion from the end of the grate 300 ~ 500mm. 4. maintain proper furnace temperature to avoid coking. The fire bed to maintain the homogeneous combustion, to avoid burning fire bed obliquely. 6. The residence time of the fuel on the grate in less than 30 minutes.

How natural gas 5 tons coal fired steam boiler in vietnam steam boiler model selection natural gas main type WNS and SZS type Both models can burn natural gas, liquefied petroleum gas, coal gas, coke oven gas, biogas, including steam boilers and hot water boilers, gas concrete how the selection of steam boilers, we take a look. Due to the different sectors of production processes, demand for steam boilers are also different, and therefore, when the gas steam boiler selection, need to have enough knowledge of the production process, in order to make the right selection and design of the boiler. 1, selection of technical parameters: gas comprising steam boiler rated evaporation, rated steam pressure, steam temperature rated, e.g., general pressure chemical production requirements are not too high, the pressure required to produce 10 kg as an example, then the boiler design pressure of 1.25 MPa is necessary to use; 2, ancillary equipment options: supporting auxiliary gas steam boiler main control cabinet, water supply pump, circulation pumps, burners, sub-cylinder, water treatment equipment, energy, a condenser, users can choose according to their own needs and price configuration; with the Earth's atmosphere deteriorating, I believe that we Chinese citizen environmental awareness is still very strong, in order to reduce pollution of the planet, we must first consider how environmentally friendly energy-saving performance, then consider fuel, gas boiler combustible gases, polluting emissions, environmentally friendly energy-saving ideas. Boiler pressures, consider the problems caused by an explosion caused by overpressure, and even carbon dioxide poisoning incidents. In the control of gas-fired boiler operation, select the better it is simple and easy to operate.

First Affiliated Hospital of Bengbu fully implement the national environmental protection policies, strict screening of clean boiler as the supply of medical supplies disinfection and ward heating equipment. Fast boiler with its focus on research and development of clean-type gas boiler two decades of experience in the industry favored. The partnership, to provide fast boiler First Affiliated Hospital of Bengbu Medical College, a WNS20-1.25-YQ one condensing 5 tons coal fired steam boiler in vietnam, in terms of design, manufacture, installation and other aspects of strict checks to enhance the thermal efficiency of the boiler as well as truly Energy saving and environmental protection.

Mill 5 tons coal fired steam boiler in vietnams to reduce pollution which method 1, leak checking and maintenance of protection: 2 mm steam leakage will cause energy losses of more than 10 tons of coal each year do? When you do not use it, you can turn it off to save energy. For water, steam and compressed air leak survey and routine maintenance, cost very little. 2, the non-contact cooling water in repeated use: Since the non-contact cooling water temperature and the quality is very good, it can be reused for desizing, scouring, rinsing and other processes. Three best source of cooling water is regenerated: sintering machine, a pre-link and compressor systems. The plant water recovery system may be installed, pipes, valves, storage tanks, and control systems. 3, reuse of steam condensate: textile mills require large amounts of saturated water vapor in the dyeing process, wherein a portion of the condensate is converted to its high temperature and purity. Water can be pumped back to the boiler to form a new steam. For those who buy steam from suppliers, or boiler is located away from the dyeing process, the condensate can be used as water washing or desizing. 4, pre-treated wastewater reuse Procedure collected bleaching, mercerizing machine, the water can be reused in other programs, there is no direct discharge of wastewater. 5, hot wash water is recovered from the hot gas in the dyeing process, large amounts of hot water are used to wash. Heat the washing water can be collected by the system plate heat exchanger to preheat the water to be sent to the next washing. 6, pre-screened coal enterprises should introduce screening spiral coal boiler technology to selection of raw materials. It is possible to improve the media tell the good, the bad quality of proportion, to avoid loss of small volumes of coal and coal calorific value. 7, maintaining steam traps traps can help maintain effective delivery of the steam plant. The valve is removed from the steam pipe and prevent further condensation water, so as to avoid heat loss and reduce fuel consumption. 8, pipe insulation pipes, valves and flanges, valves and flanges experience hot waste of resources, reducing efficiency. Steam delivery device insulated to prevent vapor loss is an inexpensive, energy-saving method of .9, the heat recovery boiler chimney smoke at a temperature of 360 deg.] C, and sometimes directly discharged into the atmosphere, there is no heat recovery. In fact, this heat can be used to preheat boiler water, steam or create a new steam system. 10, optimization of compressed air systems consume a large amount of compressed air in many parts of textile machines Mills. These instruments are prone to leakage, particularly in a threaded joint, rubber joints, valves, automatic regulator, the inflatable device and the old gasket. In addition, the use of compressed air pressure is usually based on the maximum pressure setting; reduce this pressure is feasible and would not have any negative impact manufacturing.
