direct coal fired hot air furnace, The eco-friendly steam boilers of ZOZEN Boiler can realize the ultra-low NOx emission

The year 2020 is a significant year for ZOZEN Boiler that we together overcame the difficulties brought by COVID-19, implemented the lean factory project, carried out performance appraisal in the whole company, etc. This year, as ZOZEN Boiler is undergoing a huge change from top to bottom, the performance appraisal and promotion system of front-line staff also has important changes.

Facing the challenges of 2020, Wuxi Zozen Boilers Co., Ltd. has made great progress. In July, ZOZEN's Wuwei Yili project team, with wonderful performance on project construction and management in the second quarter, was awarded "Excellent Project Team". ZOZEN will continue to provide high-quality heat supply equipment for Yili Group's demonstrative project of green production and intelligent manufacturing.

The former part of ZOZEN SZL coal fired boiler body is surrounded by membrane wall, its upper part connects with boiler drum and lower part connects with header, which forms a combustion chamber to absorb the radiated heat from furnace there are dense convection tube bundles between the back side of upper and lower drum, the high temperature smoke enters a separate economizer after flushing heat absorbing surface then discharge from chimney.

ZOZEN biomass-fired boilers refer to the boilers fueled by biomass energy, which are typically energy-saving and eco-friendly products. Biomass fuel usually refers to the agricultural and forestry wastes such as various crop straws, leaves, wood chips and so on, which are renewable and recyclable. The operating cost of biomass-fired boilers is low, which is only a half of that of gas-fired boilers. However, the initial investment cost of biomass-fired boilers is higher than that of oil-fired or natural gas fired boilers. Biomass-fired boilers are good alternatives to gas-fired boilers when replacing the coal-fired boilers. At present, the technical parameters of biomass-fired boilers are 2-75 tph (rated capacity) and 2.0-116 MW (rated thermal power), direct coal fired hot air furnace.

direct coal fired hot air furnace, Welding automation is one of the significant advantages of ZOZEN Boiler. The advanced automatic submerged arc welding process ensures the welding quality of the boiler, and the welding of each longitudinal and circumferential accepts the 100% X-ray detection; automatic tube plate welding not only greatly improves the production efficiency, but also ensures the high quality of WNS series natural gas boiler.

direct coal fired hot air furnace, PT.Mikie Oleo Nabati is an palm oil company in Indonesia. Steam boilers are used for refining, bleaching, deacidification, deodorization, fractionation and other processes in the palm oil production. The biomass-fired boilers the company ordered from ZOZEN can perfectly resolve the problems of scaling, abrasion, burning front arch and feeding hopper. The thermal efficiency of ZOZEN’s biomass-fired boilers can reach above 88%.

ZOZEN has proved its competitive advantage with its high product quality. In the future, ZOZEN will spend more time and energy on the innovation of gas-fired boilers, and capture more market share, direct coal fired hot air furnace.
