ZOZEN eco-friendly biomass pellet fired boiler supports the anti-poverty project in Heze, Shandong Province

Heze Huihao Textile Co., Ltd. is an enterprise specializing in the production and sales of weaving fabrics. In order to meet the market demands for the better and long-term development, the company invested 120 million yuan to launch a project with an annual output of 3,000 tons of knitted fabrics and 3,000 tons of rinsing knitted fabrics.

Considering the heat demands of processes such as rinsing, drying and local environmental protection standards, Heze Huihao Textile planned to purchase a set of steam boiler which burned biomass pellets as the fuel. After comparing the major biomass-fired boiler manufacturers, the company found that ZOZEN Boiler has the higher level in terms of the manufacturing strength and R&D system.

ZOZEN Boiler has focused on the boiler manufacturing for more than 30 years. After many technological changes, ZOZEN has 600 sets of advanced production equipment with high processing precision and high efficiency, which can guarantee the boiler quality, realize the large-scale production and shorten the delivery cycle. At the same time, ZOZEN also pays great attention to research and development and adheres to technological innovation. It has kept improving the biomass-fired boiler structures and has solved the problems such as low burnout rate, easy coking, ash accumulation caused by the diversification of biomass fuels.

This time, according to the demands of Heze Huihao Textile, ZOZEN customized a set of 36 tph DZL series biomass-fired steam boiler. The boiler proper is a single drum arranged longitudinally. The drum and water-cooled walls on both sides form the radiant heating surface of the furnace. The furnace is heightened according to the biomass pellet characteristics. Meanwhile, the grate adopts the suitable high temperature resistant grate bar materials to improve the grate reliability and ensure the safety production of the boiler.

It is commendable that the biomass-fired boiler also adopts the intelligent SNCR denitration system. Via the control of multiple air dampers on the grate, the ratio of primary air to secondary air can be controlled reasonably to control the furnace temperature within the range of high denitrification rate, so as to effectively reduce the original emission of NOx. After the boiler combustion, the flue gas is treated by the secondary dust removal and dual-alkali separation devices. The treated exhaust gas is discharged through an 18-meter high exhaust cylinder, which can control the NOx emission within 100mg/Nm³, so as to meet the environmental protection standards for the key control areas in Shandong Province.

ZOZEN can help users design the reasonable biomass-fired boiler systems

The biomass-fired boiler provided by ZOZEN Boiler not only provided the stable heat support for Heze Huihao Textile, but also helped the company realize the goal of energy saving and emission reduction.
