horizontal gas fired steam boiler for refine sugar
Boiler precipitator technical principles of environmental protection and the development trend in recent years, the rapid development of gas power plant boiler in the direction of large-capacity, high-parameter, either manufacturing or operations management have been close to the advanced level. Boiler and gas industry to maintain large, widely distributed, high energy consumption, heavy pollution, energy efficiency and pollution control the overall level compared with foreign countries have a certain gap, a huge energy saving potential. By the end of 2012, China's use of gas in industrial boilers 467 000 units, with a total capacity of 1.78 million tons of steam, the annual consumption of about 700 million tons of coal, accounting for over 18% of the country's total coal consumption. China's gas lower overall energy efficiency of industrial boilers, about 15 percent of its actual operating efficiency lower than the international advanced level, with great potential for energy savings. In recent years the rapid development of technology the dust bag, in particular accessory bag filter (dust bag, dust bag cage pulse valve, control of the PLC technology, etc.) to improve quickly, while baghouse 10% desulfurization efficiency can be improved It is dry boiler flue gas desulfurization one of the major thermal power plant equipment. Boiler precipitator dust is the most effective pollution control equipment. It has a high dust removal efficiency, after the flue gas-containing filter baghouse dust concentrations below 50mg / m3, even at 10mg / m3 or less, and can efficiently remove the fine dust particles. Boiler boiler precipitator not just in the production of which use can also be used in other fields of thermal power. During use of the boiler generating the flue gas and dust is inevitable, the boiler boiler precipitator dust is separated out from the flue gas, thus reducing the dust pollution and facilitate further flue gas desulfurization, denitrification process. Spark arrestor smoke dust is mainly used in some high temperature and flue gas containing process Mars. For example, the flue gas cupola, intermediate frequency furnace flue gas, a furnace flue gas and so on. The main role is to eliminate smoke sparks, to avoid burning dust bag. Spark arrestor has a variety of structural forms, cyclone, louvered like. The most effective way of collecting cyclone is, the guide vanes guide the flue gas using a cyclone-type rotational flow, after the dust and large particles Mars cylindrical guide vane duct wall collision or off. When the smelting furnace flue gas containing spark large particles, dust bag will cause damage. Mars trap can effectively trap particles Mars in the flue gas, the protection of the bag filter. The entire device by the PLC control unit, automatic cleaning, discharging and automatic temperature control and over-temperature announcer.
Process safety valve check valve gas horizontal fired steam boiler for refine sugar is one of the three safety accessories gas steam boiler, when the boiler pressure is too high, the pressure relief valve will automatically exhaust, gas steam boiler is the important safety equipment . The case of a new installation, overhaul, lack of consumer safety valve shutdown and restart more than three consecutive months, have had to re-check safety valve, safety valve to ensure accurate and reliable by the company safety officer, boiler technician, run operators, maintenance personnel together with the completion of the adjustment. Valve adjustment procedure is as follows: 1, the steam boiler when the gas vapor pressure close to the operating pressure of the safety valve, and retest check valve to the air motor exhaust, drainage accident flexibility and reliability of the electric valve, and the panel reinspection situ pressure gauge, the water level of accuracy, such as failure, not allowed to heat the school. 2, ready to call and check the quality of communication tools, a signal indicating whether the good. 3, adjust the safety valves, boiler pressure should be kept stable, pay attention to monitoring gas steam boiler drum level, and maintain normal. 4, steam boiler safety valve to adjust the pressure gauge in place of instructions shall prevail. If necessary using 0.4 or more for the accuracy of the gauge. 5, adjust the safety valve should be carried out only by descending. It should checksum gas steam boiler tuning high pressure safety valve, after the school seizure of the entire set of low pressure relief valve. 6, the following should be in the 0.3MPa, the movement preventing measures must do a good job of setting relatively low pressure steam boiler safety valve safety valve before adjusting. 7, by combustion, and exhaust steam adjust the degree of opening to the air slowly and smoothly up to the required setting pressure. 8, when the gas pressure steam boiler safety valve set pressure to rise if action is normal, then the action and reseating pressure values recorded. If action is not correct or not action should be immediately opened to the air exhaust valve, while the combustion boiler weakened, stop boost, and buck 0.3MPa or less, re-adjust the boiler technician as required by maintenance personnel, until the compliance date. (Lead or lag 0.05MPa action is normal). 9, after the completion valve to adjust gas steam boiler, boiler 0.3MPa or less down to the lifting device and can be installed and fastened to the protective cover, a braking measure required under check valve removal, then Articles 7, 8 verify until all required safety valve calibration check is completed. 10, the safety valve to adjust the gas boiler, check the results recorded in the "safety valve to adjust the recording Visa" within the participants should verify the signatures and Internet safety valve input to the corresponding data in the ledger. During operation gas steam boiler, not only to regularly check on the safety valve, at the same time, we must regularly monitor boiler inspection to ensure that the boiler fully meet the safety requirements!
Anyang City Minshan Nonferrous Metal Co., Ltd. is a collection of urban mining, renewable resources, energy as one of the economic wisdom of cleaning companies, mainly non-ferrous metal extraction and processing work. Company to conserve energy, cleaner production for the purpose of this concept coincides with the fast boiler.
