ZOZEN WNS series oil-fired/gas-fired boiler is a kind of fire tube wetback boiler with a two-pass or three-pass structure. It is equipped with foreign advanced burner, economizer and condenser installed at the end of flue gas duct to lower the exhaust temperature to 60℃, achieve the thermal efficiency of over 98% and control the emission of NOx to less than 30mg/Nm3. It has the characteristics of compact structure, small covering area, short installation period, easy operation and complete automatic control system which can realize unattended operation.
The new generation of SZL series boiler is cooperated with Shanghai Jiaotong University. It increases the furnace height, increases rotating speed, adds ash blowing device and designs ash removal system at the bottom of the grate. These well solve problems like scaling, abrasion, front arch, etc. It can also reduce the maintenance and operating costs and extend the service life of the biomass-fired boilers.
Binzhou Xinkeode Technology Co., Ltd. is a private enterprise engaged in the production and sales of neopentyl glycol, sodium formate and formaldehyde. According to the actual situation of Xinkeode’s production lines, ZOZEN Boiler recommended the SZS series gas-fired condensing boiler. This series of steam boiler adopts the large furnace design and advanced burner, which can ensure the sufficient combustion of fuel to improve the fuel use ratio. With the energy-saving equipment at the end of the gas duct, the boiler thermal efficiency can reach 98% and above to save the operating costs.
ZOZEN SZS series steam boiler is a kind of D-type chamber structure boiler with longitudinal double drums. It has a big combustion chamber equipped with the low emission burner to effectively reduce the NOx. It also adopts the full membrane tube wall structure and pressurized combustion without smoke mixture.
Shandong Luhua Group Co., Ltd. is a national key leading enterprise of agricultural industrialization in China with 24 production bases and covers industries of edible oil, condiments, vegetable processing and so on. Its annual production capacity of edible oil is 1 million tons and that of condiments is 100,000 tons. ZOZEN's SZS series gas-fired steam boiler and SZS series low NOx gas-fired saturated steam boiler have sufficient heating surface and enough steam and water space to ensure the stability of boiler indexes. Meanwhile, full membrane wall structure can ensure excellent airtightness and thermal efficiency (above 98%). ZOZEN Boiler also adopts ultra low NOx burner via flue gas circulating can ensure the complete combustion of fuel and control the emission of NOx at the same time. It is estimated that boiler's NOx emission is less than 28mg/m3, which completely meets the standards of Environmental Protection Department of Shandong Province.
Recently, ZOZEN took a field trip at the project location of the WNS boiler. The ZOZEN WNS series gas-fired steam boilers are horizontal wetback fire-tube boilers which have reasonable internal structure. An advanced low NOx burner is equipped with the boiler to reduce the NOx emission to less than 30mg/Nm3. At the same time, the burner can realize automatic air adjustment, which can ensure the sufficient fuel combustion.
This SZL series boiler is designed and developed by ZOZEN, which has the characteristics of wide adaptability of coal type, compact design and convenient installation. Benefiting from its outstanding performance advantages, this series of chain furnaces successfully won the favor of Agra Feed S.A.S. In order to improve the actual efficiency of the company, ZOZEN also customized a complete set of steam boiler system with a thermal efficiency of over 82%. Meanwhile, according to the environmental protection requirements of the region, ZOZEN also installed dust removal, desulfurization and denitration facilities to effectively reduce NOx emissions.
