Area gas boiler heating gas boiler accurate measurement method is now occupied most of district heating, but heating in the heating area, indeed never specifically talked about today Xiaobian find some relevant content to share to you, you can use to confirm. 1. Gas boiler heating area thickness measurement method. Thickness measurement method using a thickness gauge that the wall thickness of the gas boiler heating surface area wear or corrosion thinned tube, the tube is used to determine the degree of thinning. Method for checking the thickness measurement of various heating surface, particularly suitable for checking internal heating surface tubes corrosion. 2. A gas boiler heating area vernier caliper measurement. With a vernier caliper to tubes of the heating surface is easy to wear or swelling burn site was measured, in practice, typically superheater or reheater tube wall temperature measurements up areas, to verify whether the tubing expansion thick, wear or corrosion. Significance with a vernier caliper to easily burn the heating surface tubes wall temperature measuring swelling in that the heating surface tubes and the measurement site recorded measurement results, the values obtained for the measurement at the same site compared with the next overhaul, gas heating surface tubes to determine readily fired boiler burning site bulge swelling tendency, as the basis for future maintenance. 3. A gas boiler heating area of the spacer caliper measurement. Spacer caliper is in accordance with various specifications of the tube heating surface, a number of manufacturing a caliper fixed dimensions, the size of each pipe, the two or three different sizes caliper according to its production of pipe material . The caliper is the maximum value of the maximum thick carbon steel pipe expanding the outer diameter of not more than 3.5% or the maximum expansion of crude steel pipe does not exceed a predetermined outer diameter and 2.5% prepared, carried out with the maximum pipe diameter measurement caliper according to the material of the tube it can be determined whether the tube exceeds a predetermined expansion crude. The minimum caliper is the maximum amount of thinning of the tube wall thickness of the pipe does not exceed 1/3 of the fabricated, for the pipe diameter with the minimum calipers measured, based on the tube exceeds a predetermined amount is thinned. Employed, spacer caliper measurement exceeds a predetermined heating surface tubes, with high efficiency, high inspection speed, reduce labor intensity inspection personnel and so on. The maximum caliper is used to check gas boiler superheater or reheater tubes exceeds a predetermined expansion crude measurement tool, and the minimum caliper is used to check the superheater, reheater, economizer, or wear, corrosion exceeds a predetermined measurement tools.
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.
Because of its unique structure, and by the capacity of the boiler water pressure has little effect, the size and capacity can be customized according to specific user needs. Recently we like Guan China Fortune real estate company offers a 80 tons of steam and a hot water pipe 40 tons of steam boiler for rices for residential heating.
Second, if the low nitrogen emissions
