causes of too high alkalinity of boiler water

Boiler surface quality of the weld quality of the weld surface of the causes of too high alkalinity of boiler water requires requirements: (1) should meet the dimensions of weld design requirements and technical standards, weld and base metal should be a smooth transition, is not less than the height of the weld surface of the base material . (2) the weld heat affected zone and the surface does not allow cracks, pores, craters, and macroscopic defects such as slag. Vertical (3) of the pressure element, and the circumferential weld seam stitching head no undercut, partially undercut the remaining weld depth of not more than 0.5 mm. Sides undercut weld pipe total length of not more than 20% of the circumference of the tube. (4) grinding the weld surface after the elimination of defects or mechanical damage thickness not less than the thickness of the base material. (5) on both sides of the slag and weld spatter must be removed.

Fluidized Bed

At the bottom of the boiler furnace there is a bed of inert material. Bed is where the coal or fuel spreads. Air supply is from under the bed at high pressure. This lifts the bed material and the coal particles and keeps it in suspension. The coal combustion takes place in this suspended condition. This is the Fluidized bed.

I believe that many users choose the causes of too high alkalinity of boiler water, the boiler will notice a different model, corresponds to a different code. These codes represent the specific information of the boiler, as the capacity of the boiler, fuel media, whether under pressure, out of the water temperature and the like. But for people without regular contact with the boiler industry, the meaning you want to read the boiler model parameters is not a simple thing, we fast boiler for everyone summarizes some common boiler codes to help you understand them meaning.

For the continuous improvement of the province's environmental air quality, enhance people's happiness index, Henan Province Government Office issued the "2019 campaign of air pollution control implementation plan." Details are as follows.

1, to carry out special treatment industrial furnaces

Based on the melting furnace, the melting furnace, sintering machine (furnace), roasting furnace, a heating furnace, heat treatment furnace, a drying furnace (kiln), coke oven gas furnace 9 categories, to carry out an intensive investigation, the establishment of industrial furnaces Details inventory management, enhance the implementation of classification regulation. Not included in the investigation of industrial furnaces list, all included in the autumn and winter peak load shifting discontinued inventory.

2, to carry out clean alternative

Of coal, petroleum coke, residual oil, heavy oil as the fuel of a heating furnace, heat treatment furnace, a drying furnace (kiln), and actively promote the use of natural gas, electricity and other clean energy and the use of plant waste heat, heating power plant and the like instead.

3, to carry out comprehensive improvement of industrial boilers

Before the end of October 2019, in addition to undertaking tasks and will not have the alternative livelihood conditions, the province's basic complete 35 steam tons / hour boiler clean energy transformation or removal of coal-fired. Transformation methods include the removal, an alternative central heating, gas coal, coal to electricity, use geothermal, wind, solar, biomass with a bag filter. Chaigai on schedule to complete the coal-fired boilers, based on 40,000 yuan / tons of steam prize money up. Forbidden to use has been shut down and eliminate waste coal-fired boilers to cash rewards and subsidies.

4, strengthen upgrading gas-fired boiler

Before the end of October 2019, the provincial municipality and county (city) district built more than 4 tons of steam and low nitrogen gas boiler complete transformation after transformation, soot, sulfur dioxide, nitrogen oxide emissions are not higher than the concentration of 5,10,50 mg / cubic meter.

5, strengthen upgrading oil-fired boiler

Before the end of October 2019, the provincial municipality and county (city) district built more than 4 tons of steam and fuel (including alcohol-based fuel) boiler low nitrogen complete transformation after transformation, soot, sulfur dioxide, nitrogen oxides emission concentration is not high in 10,20,80 mg / cubic meter.

6, vigorously promote urban central heating

Full use of existing resources and central heating facilities, the existing large-scale heat sources and central heating pipe network in the area, in-depth investigation heating demand, and promote the rich heating capacity extends to reasonable radius and root out the potential heating, heating reduce blind spots. Before the end of October 2019, Zhengzhou, Anyang, Jiaozuo, Puyang City, built-up area of ​​central heating penetration reached more than 90 percent, Xinxiang City, central heating penetration reached more than 85%; Luoyang, Xuchang, Jiyuan City, central heating penetration reached 3 more than 80%; Sanmenxia central heating penetration 75% or more; unsealing, Pingdingshan, Hebi, 4 Zhumadian City, central heating rate of 70%; Luohe, Shangqiu, Nanyang 3 City central heating penetration reached 60% .
