4 9mw mixed gas boiler in spain, the emission level of ZOZEN gas-fired boiler is superior to international standards

Facing the challenges in 2020 which is the final year of the country’s three-year Blue Sky Protection Campaign, ZOZEN Boiler, as a benchmark enterprise in the domestic industrial boiler field, will continue to research and develop the eco-friendly boilers, which can promote the “coal to gas” policy in the Beijing-Tianjin-Hebei region and surrounding areas.

Recently, as a leading enterprise in the domestic industrial boiler manufacturing industry, ZOZEN has successfully passed the examination of Jiangsu Market Supervision and Administration Bureau and has acquired the permission to engage in the installation, maintenance and reconstruction project of pressure-bearing special equipment with a sub project of boiler installation (A grade), which is valid until the August 7, 2024, 4 9mw mixed gas boiler in spain.

ZOZEN has realized automatic welding of the longitudinal seam

The body of ZOZEN YLW series coal-fired thermal oil heater adopts an advanced structure to optimize the radiant heating surface and reduce the formation and emission of flue gas and dust in the combustion chamber; in terms of furnace body insulation, ZOZEN boiler uses high-quality insulation materials and special technology to reduce the heat loss as much as possible; and an effective dust removal structure is scientifically set up for the maintenance, operation and cleaning of the boiler.

4 9mw mixed gas boiler in spain, The main advantage of circulating fluidized bed boilers lies in the direct control of pollutant discharge during the combustion process. This type of boiler adopts low-temperature combustion technology. The furnace temperature of a conventional boiler is as high as 1400-1500°C during combustion, while the furnace temperature of a circulating fluidized bed boiler is in the lower range of 800-900°C, which can reduce the generation of NOx; meanwhile, SOx can be removed during fuel combustion by adding low-cost limestone in the circulating fluidized bed boiler.

The cold working, also known as “iron tailor”, is a kind of comprehensive technology to process metal sheet material, tubular product and proximate matter into various kinds of products without changing the cross section characteristics, which includes straightening, laying off, blanking, cutting, bending, stamping, assembling, riveting, welding, etc. At ZOZEN’s production lines, the number of cold working workers is the largest except that of welding workers.

According to the actual production demands of Lenzing (Nanjing) Fiber Co., Ltd., ZOZEN Boiler recommended the SZS series gas-fired superheated steam boilers. This series of steam boiler adopts the large-volume furnace to ensure the sufficient fuel combustion. Combined with an advanced low-NOx burner, it can easily achieve the low emission of NOx, which meets the environmental protection requirements of Lenzing Group. At the same time, in order to improve the boiler thermal efficiency, it not only uses the high-quality aluminum silicate fibers for the furnace body, but also uses high-temperature refractory mud for heat preservation. With the additional energy-saving equipment at the end of the flue gas duct, the boiler thermal efficiency is as high as 98% to save the operating costs, 4 9mw mixed gas boiler in spain.

In recent years, attention to environmental protection and sustainable development has been raised to a new height. Both Lenzing Group and ZOEN Boiler are constantly practicing the concept of sustainable development. There may still be new challenges in the future, but as a large-scale enterprise with social responsibility, ZOZEN Boiler will continue to insist on technological innovation and work with partners to achieve the unified development of economic, environmental and social benefits.
