4 tph DZL series chain grate best price environmental friendly steam boiler price for the feed industry
ZOZEN has focused on the research and development of chain grates for years and has obtained a number of patent technologies. With thermal efficiency over 82% and NOx emissions less than 100mg/Nm3, ZOZEN DZL series boilers have realized the high efficiency and low emissions goals. DZL series boilers adopt horizontal single-drum structure and a chain grate and take the lead in adopting arched tube plates and threaded smoketubes to increase heat conduction. The heat transfer coefficient of threaded smoke tubes is 1.8 times higher than ordinary tubes. In terms of manufacturing processes, ZOZEN adopts the pre expansion of smoke tubes and tube plates to eliminate the gap between them, and then adopts the welding process of argon arc automatic welding to effectively eliminate the stress and prolong the service life of the boiler. With above advantages, ZOZEN has been one of the most popular industrial boiler brands in the feed industry.
4 tph WNS series condensing gas-fired best price environmental friendly steam boiler price project for universitiesFounded in 1958, Changchun University of Science and Technology has three campuses with a building area of 627,000 square meters and a total of 29,820 students. Therefore, the boiler plays a non-negligible role in ensuring the daily needs of teachers and students.Facing the severe situation of environmental protection, Changchun University of Science and Technology decided to upgrade the original boilers. ZOZEN won the trust of Changchun University of Science and Technology with its advantages of safety, efficiency, environmental protection, energy saving and rich experience in boiler projects. In order to fully meet the needs of the university, ZOZEN customized a branch of WNS series gas-fired steam boiler systems. In terms of safety, ZOZEN has a complete and strict quality inspection process, fundamentally avoiding hidden dangers of quality, meanwhile, more than ten kinds of safety protection interlocking devices such as the failsafe interlock of burners to ensure the safety of the boiler during operation. In terms of environmental protection, WNS series natural gas fired boilers adopt self-developed combustion optimization control technology, combined with advanced low NOx combustion devices, effectively controlling NOx emissions below 30mg/Nm³, which is in line with environmental requirements. In addition, in order to achieve better energy-saving effect, ZOZEN installed energy-saving devices on the tail of the boiler flue, so that the thermal efficiency of the boiler can reach as high as 98%.
In considering measures for the protection of the environment the utilization of naturally occuring materials, which are considered as CO 2-neutral, as well as the question of waste treatment are very important.Biomass combustion have various types such as stoker grate-fired boilers, suspension-fired boilers, fluidized bed boilers,including co-firing and so on.
To continue to improve urban air quality, to ensure the safety of winter heating, heating Dalian Municipal Construction Committee Office will strictly enforce the "Clean northern winter heating plan (2017-2021 years)" (the "Plan"), and strive to achieve clean heating.
"Plan" put forward, Dalian will gradually increase clean heating rate, adhere to clean coal-fired central heating, local conditions of use of electricity, natural gas, solar energy (3.250,0.04,1.25%), biomass and other clean energy heating, heat storage are encouraged to promote electric heating type and other ways; the existing thermal power plant, waste heat of industrial enterprises depth potential, priority use of heat source heating to achieve ultra-low emissions; research to develop clean energy heating pricing policies; supporting natural gas pipeline network to speed up urban construction, in the implementation of the gas source, guarantee under the premise of residents to use gas, natural gas heating in an orderly way.
Continue to optimize heat distribution. Speed up the construction of heating pipe network, out of network coverage and bulk coal fired boilers within range. In areas do not have the cogeneration district heating conditions, the existing multiple small coal-fired boilers, alternative construction of large-capacity coal-fired boilers in accordance with the principle of equal volume.
2018, the city built-up area basically integrated heating. 2019, the county level and above the basic integration of urban built-up area of heating. Before the end of 2020, according to the special plan for urban heating requirements, the county level and above in urban built-up area within the range of 300,000 kilowatts and heating cogeneration power plant over a radius of 15 kilometers, coal-fired boiler and does not meet the ultra-low emissions of coal-fired power plants all closed down integration.
2018, above the level of removal of industrial parks and 10 tons of small coal-fired boilers 49 units, 265 units and 10 tons of banned coal-fired boilers since 2014, new registrations. 2019, to improve the standard phase-out of coal-fired boiler, expand the scope to promote the elimination of urban built-up area of 20 steam tons / hour (or 14 MW) and coal-fired boilers. 2020, except in accordance with urban heating heating boiler special plans need to retain outside built-up areas at the county level and above cities 20 steam tons / hour (or 14 MW) and coal-fired boilers to be eliminated.
Gradual development of ultra-low emission ultra-low emission coal-fired power plant renovation, started in 2018 and the North Sea thermoelectric thermoelectric Taishan ultra-low emissions renovation, completed in 2019 Heung Hoi coal-fired thermoelectric power plants and other enterprises reform, in 2020 to complete a full ultra-low emission coal-fired plant transformation .
