average amount of coal taken by a boiler

From March 18 to start, Lujiang County, Anhui Province north of the Market Authority on the area of ​​internal security to carry out a special inspection of average amount of coal taken by a boiler pressure boiler; To ensure the safe operation of this special equipment, complete elimination of security risks.

The inspection mainly troubleshoot and eliminate hidden dangers in the management and operation of the boiler links exist, focus on examination of whether to establish safety management systems and procedures; whether to set security management or part-time security management staffing; whether workers with valid work certificate for employment; boiler operating records, inspection records and shift recording is complete; if the boiler for the use of registration; whether the inspection within the validity period; check valve is within the validity period, the pressure gauge whether the test within the validity period. Up to now, law enforcement officers dispatched 27 people, focus on examination of 12 times the focus of special equipment supervision units, hospitals, schools, boiler 20 times, do not meet the specified use in accordance with the boiler "Special Equipment Safety Law of People's Republic of China." requirements, issued a supervision instructions, requires immediate rectification unit, for there is no regular inspection of boilers or unqualified, shall not be put to use.

wns oil and gas average amount of coal taken by a boiler details

The wns series oil and gas boiler is a fire tube boiler produced by ZG boiler. And WNS series gas and oil fired boiler is the sub-project of high efficiency (up to 95% thermal efficiency) and eco-friendly boiler under the World Bank’s GEF Program. As you can see from the name, this boiler fuel design is natural gas, oil, biogas, etc. These fuels have advantages in some respects compared to biomass fuel, coal and other energy sources. These fuels are transported in the form of pipelines. This means that the oil and gas boilers do not need to be treated and stored for combustion, which reduces the footprint of the boiler plant and reduces the cost of the site.

Environmentally friendly gas-fired average amount of coal taken by a boiler combustion gas combustion five characteristics: In recent years, many cities frequently haze, caused widespread concern and heated debate. China is in the energy structure adjustment period, the task is urgent, the situation is very grim. Energy saving boiler gas boiler is the time to show their talents, its good energy efficiency and excellent environmental capacity, more and more enterprises of all ages. Here we analyze the characteristics of its advantages from the combustion of gaseous fuel. The fuel gas is a highly efficient, clean energy, its relatively low ignition temperature, the flame may spread rapidly to all parts of the furnace, the rapid combustion, facilitate gas, mixed with the combustion process is automatic, has the following characteristics: (1 ) virtually zero pollution combustion characteristics coupled with substantially does not produce ash, nitrogen content and sulfur content should be much lower compared to the fuel oil and coal, flue dust contained in the combustion rarely, very help protect the environment, essentially non-polluting combustion, even the most stringent environmental requirements of the region also ease of use, while gas fuel delivery pipes are based, will not produce ash, during transportation and storage leakage of harmful gases, dust and noise pollution does not occur. (2) facilitate adjustment of combustion. Transport pathways is the fuel gas conduit, through the valve, damper adjusted accordingly, adjust the air consumption can be achieved quickly adapt load changes, low oxygen combustion can be realized, thereby improving the thermal efficiency of the boiler. (3) Good job. Compared with the fuel oil, fuel gas from the transport duct, direct supply, eliminating the sump, fuel tanks and other household members. In particular compared to the heavy oil fuel, eliminating the need for heating, thermal insulation and other aspects. Gas system is relatively simple, the operation is relatively easy to manage, easy to automate. (4) easy to adjust the amount of heat. When LPG combustion, part of the air is added, to avoid the part of both the explosive range, you can adjust the amount of heat. (5) There are some disadvantages gas fuel, when mixed with a certain proportion of air, it will form an explosive gas, most of the fuel and the gas composition to humans or animals asphyxia toxic, so the security is very high. Boiler attaches great importance to the security of energy saving gas boiler in the production, testing process strictly guard the quality, as long as the practices in use, accidents will not happen.

Cooperation with South Korea development of large-scale circulating fluidized bed boiler. In extensive research on the basis of the mechanism for circulating fluidized bed combustion technology with sufficient awareness, especially in the hydrodynamic characteristics of circulating fluidized bed, a circulating fluidized bed coal and special fuels (anthracite, coal, coal, raw biomass fuels, coal, petroleum coke, etc.) of the combustion characteristics of a circulating fluidized bed furnace heat transfer characteristics and tail heating surface, the control process pollutants (SO2, NOx and heavy metals) circulating fluidized bed combustion, circulating fluidized Key components such as splitters bed, feed back mechanism and external fluidized bed heat exchanger. The main fluidized bed combustion test rig owned are: cross-section of 200 × 200 high as cold circulating fluidized bed test stand 4000, cross-section of 200 × 200 high of 4000 circulating fluidized bed thermal test bench, sectional as high as 500 × 500 6000 circulating fluidized bed thermal test bench, cross-section of 350 × 350 high as 10,000 hot circulating fluidized bed test bed 1MW fluidized bed combustion test stand and vortex. In addition to research in the laboratory scale test rig performed, still 75t / h circulating fluidized bed boiler and 220t / h circulating fluidized bed boiler exhaustive testing, to obtain large flow boiler, combustion, heat transfer, pollutant Characteristics emissions.

Coal Properties and its influence on Boiler Pankaj Ekbote

Coal properties are evaluated by different methods. The most commonly used methods are Proximate and Ultimate analysis of the coal. Proximate analysis gives the Moisture, Ash and Volatile matter, while the Fixed Carbon is found by difference. Ultimate Analysis gives the elemental composition of the coal.
