steam boiler for sugar mill

In recent years, Ningbo municipal government attaches great importance to environmental protection, air pollution prevention and control work to strengthen the organization and leadership, the establishment of a multi-sectoral collaboration to air quality at the core of the atmospheric environment management systems. And introduced a new quality of atmospheric environment deadline for compliance plan, as follows.

Strict implementation of total coal consumption control, to further optimize energy consumption structure, strive to 2020, coal consumption accounts for the proportion of primary energy consumption control in about 40% of coal consumption is not higher than 2011 levels, and completely cut coal province issued the task .

Strengthen management work focused on coal-fired projects, continue to promote the elimination of the transformation of small coal-fired boilers. 2019, phasing out 10 steam tons / hour of coal-fired boilers and, in 2020, the county level and above urban area basically eliminated tea furnace, operating a stove, grain storage and drying equipment, coal-fired facilities; basically eliminated the city's 10 -35 steam t / h coal-fired boiler; 35 t steam / hour and more polluting fuels and ultra-low emissions energy boilers complete transformation.

Strengthening coal quality control, within the city limits the use of ash> 16%, sulfur> 1% low-quality coal, fuel encourage high value, low sulfur, low ash blending works. 2019, the establishment of the city's coal regular testing, sampling tests system. In 2020, the city's clean coal utilization rate of 90%.

Increase natural gas use, and actively promote major infrastructure construction official website of natural gas, LNG receiving station and other utilization of natural gas, natural gas Daly improve utilization levels.

Enhance the energy efficiency of industrial enterprises. Actively promote advanced energy conservation projects integrated coal demonstration projects, large-scale generating units coal consumption reached the advanced level of the same type of unit.

Development of central heating, central heating project to optimize the layout, promote industrial parks focused on central heating. Focus on industry gathering area, industrial park development of cogeneration, and encourage qualified development of thermoelectric cooling area for the triple. Further improve the matching of heating pipe network, construction of efficient, fast heat pipe network. 300,000 kilowatts and above cogeneration power plant 15 kilometers behind the small coal-fired boilers and coal-fired thermoelectric heating within a radius of all closed down integration.

In general, many factors economizer boiler volume and price, expected results and other gas boiler related, if you want to understand the specific price of energy conservation, need to combine their own needs to communicate with professional and technical personnel.

When the boiler heat load is gradually increased (e.g., above 30% rated load), increase flow through the screen steam superheater tube wall will not be sufficient cooling, a higher temperature tends to the wall, even over temperature. At this time, the steam temperature should be adjusted using a desuperheater can reduce the inlet temperature of the platen superheater, increased flow through it and its subsequent heating surface of the platen superheater safety factor is improved.

What is the main material fast boiler is? Why compared to other boiler plant products, lighter weight fast boiler?

For the boiler pressure, the boiler shell, sheet grade boiler furnace using a special plate (Q245R grade, in line with GB713 "boiler pressure vessel steel plate") (20g original 20R and combined grade), pipe tobacco grades are effective 20, in line with GB3087 "low and medium pressure boiler seamless pipe" for the working pressure ≤1.6MPa.
