Coal occupies a large part of our energy economy, but coal brought sulfides, carbides, dust, ash and other harmful substances are also severely affected the people's living environment and ecological environment. At this stage, China's major provinces and cities in the related industries of coal fired desain boiler change grates released specific remediation programs. By treatment of coal-fired boilers, can effectively promote air pollution control and bulk coal governance work.
Hebei Province was polluted our province, many kinds of heavy industries, heavily polluting enterprises, geographic and congenital conditions are not conducive to the spread of pollutants, and other factors lead to high emissions of air pollutants in Hebei Province.
In recent years, Hebei Province, through the management of coal-fired boilers, the "coal to gas", "coal to electricity", and many other measures to enhance the governance of the ecological environment, improve people's happiness index of blue sky. According to statistics, as of the end of October this year, Hebei province has eliminated emissions of less than 35 steam tons / hour (including 35 steam tons / hour) coal-fired boiler units 6492, a total of 12744 tons of steam, respectively, to complete the annual task of developing 96% and 95%; for the emissions amounted to more than 35 steam tons / hour of coal-fired boilers transformation process, has been the transformation of 158 units totaling 12185 tons of steam to complete the annual task of developing 70% and 95%, respectively.
Future, Hebei Province will continue to carry out renovation work on coal-fired boiler more specific details of. Through the establishment of this ledger management mode, regularly check and keep track of coal-fired boilers governance; development of special treatment programs to strengthen the "coal to gas", "coal to electricity" transformation content; relevant policies to achieve strong support and assistance encourage.
This year, the environmental protection departments in Hebei organize multiple ecological environment and comprehensive management of air pollution inspection work, as one of the key phase out coal-fired boiler inspection work has been widely attention. For no control measures, emissions exceeding the bulk coal fired boiler, remediation process according to the law or banned.
Hebei Province will further improve control efforts obsolete coal-fired boilers. The next stage will be formulated "boiler emissions of air pollutants, Hebei Province, local standards," for the local coal-fired boilers do not meet the standards of remediation and prevention measures to strengthen inspections of coal-fired boilers have been eliminated to prevent burning complex phenomenon occur.
Maintaining the environment and sustainable development is an important prerequisite for China's economic and social development. The provinces and cities in response to national policy development environment, make specific control measures, Hebei provinces and cities will also combine their own situation, the air pollution control work carried out in the end.
Condensing gas desain boiler change grate is a steam boiler on the basis of ordinary gas, the additional condensate recovery technology, fully optimized in terms of combustion, the furnace structure, the heated area and heat transfer equipment, so as to enhance the thermal efficiency of the boiler to a large extent , so that sets energy-saving, environmental protection in one.
Regular boiler safety training to employees, promote employee safety awareness to develop.
New desain boiler change grate, gas or coal-fired choose? Many users in the selection of a new boiler, there are a lot of doubts. For example, choose to use the more common coal-fired boilers do? Or the use of cleaner gas-fired boiler it? Xiao Bian from the following aspects to compare your focus to help you better understand the boiler equipment.
The fuel is shuffled into the combustion chamber using stepped grates, which cause the fuel to dry quickly and then combust. By varying the grate speed, you can allow for a wide variety of fuel with varying moisture content (usually up to 60%). As combustion occurs, ash is produced, which falls off the end of the grate.

Detroit® Hydrograte Stokers. Fine particles of fuel are burned in suspension assisted by the overfire air system. Coarser, heavier fuel is spread evenly on the grate forming a thin, fast-burning fuel bed. The combination of suspension and bed burning makes this method of firing extremely responsive to load demand.

Grate firing. It now is used mainly for burning waste and biomass, but also for smaller coal furnaces. Capacities 0.3 to 175 MWth in industry and CHP Fuel fired per grate area 1-2 MW/m 2, maximum grate area 100 m 2 Grates are typical only suitable for coarse particles, for fine particles a spreader is required, increases max. capacity.

boiler capacity can be obtained by increasing grate size or by more intense natural or forced draft (0.50 to 0.60 in. for a combustion rate of 40 to 45 lb. per sq. ft. of grate per hour), but states that high and sudden over loads are best met by forced-draft chain grates burning 55 to 60 lb. bitu minous coal per sq. ft. per hour, with air at 2 in. pressure distributed through

Fluidised bed boilers represent a technological advancement on grate boilers. The decisive advantages are in the greater flexibility in fuel parameters (e.g. heating value band) and lower emissions. The boiler integrated fluidised bed is equipped with an open nozzle grate to remove coarse particles such as stones and ceramics.
