The first half of the large coal boilers end of the oven wood oven, after completion of the coal oven according to the requirements, at this time, should increase the degree of opening of the blower, draft fan slightly open, close the door, ash door, to further improve the smoke temperature, to bake the purpose of the dry furnace wall.

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.

With the development of the economy, people begin to seek for a new type lifestyle and they have higher requirement to the living environment. Green economy and sustainable development have become the belief of modern people. In Beijing, more and more large coal boilers rooms will be turned, and the energy shift to coal burning to clean energy ---natural gas. It is understood that this year Beijing will build a number of gas pipeline in 47 projects, 52 boiler rooms “from coal to gas”, to provide gas source. After this 52 boiler rooms renovation completed, it can be reduced to about 316,000 tons per year of coal-fired to reduce sulfur dioxide emissions of about 3,839 tons, about 1,287 tons of nitrogen oxide emissions. In recent years, Beijing continues to increase efforts to adjust energy structure, promoting clean energy from coal to work. ZG Boiler is one of the natural gas fired boiler manufacturers, and it is committed to design and manufactured industrial boiler heart and soul.

But in recent years, the environmental protection department for review and coal-fired equipment requirements become more stringent, coal is gradually withdraw from the stage of history. Third, Electric Electric large coal boilers is the boiler pressure controller microcomputer, via the LCD display having a backlight in its built-in and let the operating state of the boiler is clearly visible. Throughout the operation just need to gently press the button will be able to easily complete, and display and control functions inside the built-in controller is complete. This type of boiler pressure hydropower separate electrical heating mode, is also safe and easy maintenance, easy to clean and replace them, is very convenient.
