coal fired double drums chain grate hot water boiler

Inter-regional Pingdingshan Coal Industry Group Co., Ltd. by the Pingdingshan Shenma Group and two Chinese top 500 enterprises founded by restructuring, cross-industry, cross-ownership and transnational business of large state-owned energy and chemical group, under the People's Government of Henan Province , is the most complete variety of coking coal, thermal coal production base, has Asia's largest chemical production base in nylon. Carefully selected and comparison, fast boiler Pingmei cooperation with party has chosen to provide a 2 tons of steam electric steam boiler (WDR2.0-1.25-II) by a fast side.

Hot water boiler item to check what internal checks and the use of coal fired double drums chain grate hot water boilers prepared in the furnace and flue inspections of boiler accessories, check the automatic control system, checking of ancillary equipment, inspection equipment burning auxiliary heating surface check the hot water boiler must be done before running some tests, these tests are quite a lot of us, it is possible because of our neglect and causing very serious consequences. Therefore, we must forestall, be sure to carefully check the following before the hot water boiler operation. 1, including the use of internal inspection and boiler ready. 2, inspection, and furnace fouling and debris inside the flue in the furnace and flue should be cleaned. Flue duct and damper, the shutter must be complete and compact, flexible switch, opening and closing accurately indicated. 3, check the boiler accessories, check the safety accessory is intact; cock is rotating flexible, easy to use; all kinds of instruments and controls should be complete, good, clean. After passing the examination, should the gauge cocks in working condition. 4, check the automatic control system. 5. Check the accessory device. 6, inspection of the combustion apparatus, the combustion apparatus is intact inspection; mechanical transmission system, coal handling system, the ballast system test switch normally; spring-loaded safety level of a gearbox should be appropriate, well lubricated; coal shutter indicate the correct scale. iron eagle neat, well, turn the ballast plates full, flexible movement. 7, the auxiliary heating surface of the inspection, check the auxiliary device (fan, blower, pump, etc.) are firmly connected coupling; proper belt tension triangle; oil should be good enough; cooling water flow. After passing the examination, installed security guard, respectively, commissioning, and note the current when idling.

Electrical difference between the boiler and gas boiler no real good, only for it or not. (Direct thermal electric boiler in the building standards are not allowed in the following description of an electric thermal storage boilers, there is a corresponding electric thermal storage boilers local standards) investment aspects of the common gas boiler cheaper than electric boilers at the beginning, but also the gap between the number of specific distinction, gas brand boiler size, with or without condensate recovery and technical maturity; brand electric boiler, the applicable type. Related both construction conditions, such as plumbing, gas station; selecting high and low voltage power, power distribution construction. Gas heating season in general calorific value / purity of non-compliance (even if the contract is more explicit), compared with the calorific value of the basic electrical 1: 7, the proportion of LNG to be higher, lower coal bed methane (calorific value is multiplied by the thermal efficiency of the device ). In this case, electricity savings of about 1/3 than gas, according to the grapevine, is expected this year, Liaoning low power dropped to less than 0.3 yuan (business), that electricity than the gas savings is estimated to be more than half. It covers an area of ​​respect, if the construction of the gas gas station, then it must be a space-saving electric boiler and electric boiler is the basic module assembly, according to the actual situation; and gas boiler explosion venting port and need a certain security area. In terms of energy, electricity is no waste, waste gas, waste water, renewable energy, gas or have emissions, and fossil fuels are not renewable, although the state vigorously outsourcing, but in the long perspective, the decline in the price of more space large, but also more conducive to use, especially Valley electric. Finally, if it is 30 000 m2 of non-continuous heating conditions (such as schools, shopping mall, office, public venues, factory, warehouse, etc.), recommended to choose electric thermal storage boilers, the best choice for 10kv high voltage device, you can save some investment, and the province as well as policy. But if the area is less than 10,000 m2, the election 0.4kv low-voltage equipment is also good. Equipment and electric boilers are run automatically, without someone on duty, usually around six meters do not consider lifting frame height coefficient, the heating time can independently control these areas compared to the municipal district heating is also very advantage.

Gas and coal-fired steam boiler steam boiler compare what are the advantages of (1) from the traditional economic point of view and our energy structure, coal-fired boilers due to the low one-time investment costs of popular people favored, especially in the rich coal resources , green area less demanding people prefer to select it. But in resource-poor coal, coal prices are not low areas of oil, gas and coal compared to a certain competitiveness. Another reason people like coal stove is easy to operate. But coal-fired boiler pollution: waste, emissions, waste water, "three wastes" and taste, governance Yijiao difficult (especially desulfurization, coal-fired boiler desulfurization technology currently has achieved some results, but the high investment costs, complex operation, covers an area of large), from the social perspective should limit the use of coal-fired boilers. Soot emissions (2) oil-fired boilers, although lower, but its emissions of harmful NOX, SOX gases are causing "photochemical smog" and acid rain culprit, you want to be like governance as coal-fired boiler soot emissions control. (3) gas boiler has a small footprint, less pollution emissions advantages, but also the cost of the boiler room is not set up, the use of natural gas fuel prices, operating costs lower than oil-fired boiler. (4) not only set in three furnaces comparison, gas boiler lower costs and operating costs, and its social benefits are incomparable. Natural gas is the cleanest fuel, is the least polluting fuel emissions, gas-fired boilers will be the development trend of boiler final.
