4, water supply equipment: water pump water supply through the water into the boiler by the processing device to.

5, the air blowing apparatus: the air blower means through application exports the furnace air preheater and a coal grinding heat.

Mass of flow = 5 ton/hour (i accept) = 5000 kg/hour = 5000/3600 kg/sn= 1,39 kg/sc. 3,571 MW = 3571 kw = 1,39 . (h-200) h= outlet enthalpy of boiler h = 2769 kj/kg (this value must stay at superheated region) . We must look to superheated region at thermodynamic tables.

Recently, Guizhou Province to combat air pollution, protecting and improving the quality of atmospheric environment, the protection of public health, promote the construction of ecological civilization, and promote comprehensive, coordinated and sustainable economic and social development, in accordance with the provisions of "People's Republic of China Air Pollution Prevention Law" and relevant laws and regulations of atmospheric pollution prevention and control regulations to be amended.

Article XVI: prohibits a planned urban area built or expanded cement, coal chemical, coal-fired thermal power, coking, metallurgy, ceramics and other serious air pollution industrial projects.

Article 24: Prohibition by waste-water treatment, tampering or falsification of monitoring data, in order to avoid on-site inspection for the purpose of the temporary shutdown, open the emergency discharge channel non-emergency situations, abnormal operation of pollution control facilities and other atmospheric discharge atmospheric way to avoid regulation contaminants.

Article 39: It should be the overall planning of urban construction, coal-fired heating in the region, promoting cogeneration and district heating. In the central heating pipe network coverage area, a ban on new or expanded scattered coal-fired heating boilers have been built coal-fired heating boilers can not discharge standards, should be demolished within the prescribed period the city government.

Shall manufacture, import, sale and use do not meet environmental standards or requirements of the boiler.

41: partial restriction sulfur, high ash coal mining, mining prohibition radioactive and arsenic and other toxic substances than standard coal. New coal mines must simultaneously supporting the construction of coal washing facilities. Have been built coal mines, it should be in accordance with national requirements, supporting the deadline for the completion of the coal washing facilities.

Prohibit the import, sale and burning of coal does not meet quality standards, to encourage high-quality coal burning.

Prohibit the import, sale and burning does not meet the quality standards of petroleum coke.

3, service system

Good condensing gas boiler manufacturers usually have a sound service system, which is also the user to pick one aspect manufacturers need to focus on. User intends to buy equipment from equipment manufacturers began to issue advice to the installation after purchase, debugging, and then run late inspection and maintenance of boilers, boiler technician needs and docking. Good service quality factory will arrange professional pre Commissioner and the user butt, to be understood that the information is completed, the customer service staff will recommend an appropriate model of the device according to user needs. After confirming the completion of the whole chain, if the user side still have questions or boiler failure, can promptly contact manufacturer's service department.
