Sewage disposal has always been a difficult problem in the paper industry. Although the sewage treatment system has solved the sewage, it has brought a lot of new problems of biogas emptying. ZOZEN launches the biogas boiler for paper mill. With professional and technical advantages, it connects papermaking sewage and production heat in series to build a circular economy industrial chain.

ZOZEN 4 ton capacity biogas boiler in a paper mill

Jinchang Paper Industry Co., Ltd. is a professional paper-making enterprise specializing in the manufacture of corrugated paper, which produces a large amount of biogas every day. Then the user introduces a 4ton 16bar steam boiler burning biogas to provide heat for production.

Biogas is a kind of green renewable energy with large heat amount, but as boiler fuel, there are still many technical difficulties to be overcome, such as unstable fuel pressure, easy corrosion and high pollutant discharge. Through in-depth study of biogas composition and combustion characteristics, ZOZEN Boiler has realized the large-scale biogas boiler.

ZOZEN Boiler has designed a solution of SZS series biogas boiler. The boiler adopts a customized special burner for biogas, which can reduce the influence of hydrogen sulfide in biogas on low-nitrogen combustion, thus ensuring clean emission and meeting the environmental protection requirements. At the same time, in order to avoid low-temperature corrosion, ZOZEN boiler has set a reasonable exhaust temperature and upgraded the material of condensing economizer, which can effectively prolong the service life while improving the system efficiency.

Also, the intelligent operation system of ZOZEN biogas boiler has realized the automatic interlock with user's biogas output. The automatic adjustment of boiler load can better adapt to the fluctuation of biogas output, so as to achieve the goal of unattended and fully automatic operation.
