2.8MW gas-fired thermal oil heater project in MauritiusWith outstanding advantages of quality and performance, ZOZEN thermal oil heaters have established a good reputation in the international markets. Recently, ZOZEN YQW series thermal oil heaters gained favor of SOTRATECH in Mauritius. SOTRATECH is an energy company engaged in rational utilization and sustainable development of energy, and it is committed to providing users with systematic energy solutions. This time SOTRATECH undertook a major project of a local textile mill. An energy-efficient thermal oil heater has a direct impact on the quality of the whole project, which provides heat energy for dying, printing, drying and other product progresses in textile industry. Therefore, SOTRATECH was very careful in the selection of the thermal oil heater. SOTRATECH ultimately chose ZOZEN as its thermal oil heater supplier after a series of comparative studies. The director of SOTRATECH expressed that ZOZEN thermal oil heater featured advanced production technology and strict inspection, which fully ensured the quality and performance. After learning the actual condition of the project, ZOZEN provided SOTRATECH with a set of 2.8MW YQW series gas-fired thermal oil heater. The heat exchange surface of the thermal oil heater adopts multi-loop round coil tube structure, which features high security, sufficient heating surface and high thermal efficiency. The waste heat boiler, air pre-heater and economizer are installed on the tails of the thermal oil heater to effectively save energy and reduce consumption.

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masses of people, as well as many businesses family support; many enterprises to actively upgrade and elimination of outdated equipment and production capacity.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.

The first is the gas boiler thoroughly cleaned, since it is not used for a long time, then the boiler from the inside out is bound to accumulate a lot of dust, it is only after washing clean, in order to clearly finds the actual condition of the boiler.

Flue gas temperature is a reaction boiler design, operation and comprehensive standard equipment health parameters, is the main reason affecting the thermal efficiency of the boiler. Normal boiler flue gas temperature of about 220 deg.] C, was calculated per cigarette increased temperature 10 ℃, the thermal efficiency will be reduced by 1%.
