Dongguan City, Guangdong Province in phasing out coal-fired boilers to replace the environmental transformation, biomass boilers in industries packaging, leather, clothing, textile and other widely used. However, biomass boilers still present drawbacks: If insufficient biomass combustion, typically generate a lot of dust, nitrogen oxides and other pollutants, improving PM2.5 concentration, air quality.

Dongguan City Atmospheric Office official said that since the Dongguan started Blue Sky Battle since, the city ton output capacity the courage to decisively eliminate those high pollution and high emissions industries and enterprises, won the majority of the masses of people, as well as many businesses family support; many enterprises to actively upgrade and elimination of outdated equipment and production capacity. In the eco-friendly background, out of high pollution equipment is the trend.

Transformation and upgrading of enterprises demand, government support policies have, inside and outside the echo, Dongguan out of biomass boilers into the fast lane. As of January 10, a biomass boiler out of the task of the city within 31 town street in Shilong, South City, the nave, Ma Yong, Hou Jie, stream, Feng Gang, Xie Gang, Chang Ping, Shek Pai, Chashan 11 Towns in the completion of the task of eliminating all living matter within the jurisdiction of the boiler. In addition, Long, Qi Shi, Tangxia, Sha Tin Kau five towns out of the completion of more than 90%, the remaining 15 Towns also have the confidence out of the task in the year 2019.

While out of the biomass boiler, Dongguan City, accelerate the pace of construction of gas pipeline to provide clean energy for the needs of the enterprise.

Atmospheric Office official admits:. "A few years ago, the city lags behind the construction of the gas pipeline, laying of pipe network coverage area of ​​a small number of enterprises in the coal phase-out of high-polluting fuels, the use of biomass boilers as an interim energy supply equipment, there are also often allowed to change the fuel business, steal burning coal. "but now, due to the environmental protection departments to actively coordinate the town street, village (community), industrial areas, and vigorously promote the construction of natural gas pipeline, starting from the source to provide clean energy for businesses, stealing burn the behavior of coal is greatly reduced.

Over the past year, the city has a new natural gas pipeline 256.6 kilometers, 530 companies have security using natural gas. The city urban management department based on the actual distribution of useful gas needs of enterprises to develop business for the city's more than 600 natural gas pipeline construction plan and coordinate the new Austrian, Xinghua, often positive and three gas pipeline company to carry out construction work to ensure that the natural gas pipeline construction project smoothly, so that more companies access to clean energy as soon as possible.

According to statistics, date, Dongguan City gas pipeline or central heating station accessible area of ​​660 biomass boilers, has eliminated 572 units, 41 enterprises have to apply for the boiler out of subsidies.

We interpret separate premix condensing gas boiler this vocabulary.

First, the premix

First, the performance is good or bad now many boiler manufacturers have introduced advanced condensing boiler, through the use of "condensed" this technology, ultra-high thermal efficiency of the boiler. To fast boiler, for example, the use of condensing technology star product - one horizontal condensing gas how does a steam boiler heating system work is a lot of food, chemical, transportation and other industries widely used products, this type of boiler can easily achieve more than 104% of ultra-high thermal efficiency, fuel combustion, enterprises save a lot of costs into the boiler. Second, environmental protection is central to whether the frequent mention of the "Blue Sky Battle Plan" or environmentally friendly provinces and cities nationwide avalanche of documents, marked the country is heading in the direction of the whole society to improve the quality of atmospheric air. Energy as a power boiler, remediation is the main target, currently more than 35 cities have restricted new steam tons / hour and below the coal-fired boilers, gas boilers become an excellent alternative to the hearts of the boiler unit. In the long term, the use of gas-fired boiler or to replace coal-fired boilers to gas boilers are the sooner the better. Third, the fuel used in the boiler from the safety point of view, the use of natural gas pipeline sealing, users use a boiler, pipes only need to build a good connection, and open and outage work according to the instructions to complete the operation of the boiler, convenient and safe. Moreover, many large gas boiler also on the safety valve, the entire instrument made fans and connections have made a stronger treatment, basically to maintain the boiler more than 20 years of service life; if companies strictly abide by the Code of Practice boiler safety, regular maintenance, check the time, life can even exceed 20 years to reach longer.
