ZOZEN Boiler Assists Large State-Owned Enterprise to Improve the Comprehensive Utilization of Phosphogypsum

Phosphogypsum is a kind of solid waste material generated from the production of phosphate and phosphoric acid. China is a big country that uses phosphate which causes serious pollution. With its professional skills in boilers, ZOZEN Boiler has become the supplier of thermal oil heater for Wengfu Zijin's annual output of 200,000 tons of building gypsum powder project, providing as much help as possible to solve the problem of phosphogypsum.

Boiler equipment supports the comprehensive utilization of phosphogypsum

It needs crushing, frying, modification and finished products to transform industrial waste phosphogypsum into a new type of environmental protection building material. In this process, a great amount of high-temperature heat energy is needed for drying and calcination. Therefore, industrial boiler has become an indispensable energy equipment in the production line of comprehensive utilization of phosphogypsum.

Facing the boiler demand of this project, ZOZEN Boiler recommended the thermal oil heater. Thermal fluid is the heat-transfer medium for thermal oil heater, the system has a long heat preservation time, which can ensure the continuous and uniform temperature during heating and stable quality of phosphogypsum products. At the same time, compared with steam boiler, thermal oil heater can obtain higher working temperature under lower working pressure, which meets the pursuit of high temperature in phosphogypsum processing.

ZOZEN chain grate thermal oil heater is not only reliable in quality, but also has the advantages of energy saving and emission reduction, which is in line with Wengfu Zijin's green development concept. The manufacture of square coil pipe in pipe bender to pre-bend and then butt joint. No forced shaping. Matching different fuels, the grate, front and rear arch and airflow distribution are optimized to ensure full combustion of fuels, and the thermal efficiency is higher than that of products of the same furnace type in the market.

In February this year, the commissioning run test of Wengfu project was successful in one time. All parameters of the products exceed the domestic level in the same industry. The project has become a major breakthrough in the comprehensive utilization of phosphogypsum.

At the same time, ZOZEN Boiler is also helpful to providing stable heat source.  ZOZEN Boiler will also pay attention to the boiler operation in real time, and provide professional technical guidance for Wengfu Zijin in time to ensure the normal operation of the production line.
