Project Overview

This used biomass cogeneration unit is a complete, ready-to-deploy CHP asset built for industrial steam and power production. This used biomass cogeneration unit features two sets of 75t/h CFB boiler matched with two 15MW extraction turbo generator assemblies. The CFB boiler and extraction steam turbine form the core of this used biomass cogeneration unit, making it a mature used thermal power plant and used cogeneration power plant option for buyers looking for reliable biomass power generation equipment. As a relocatable power station, this used biomass cogeneration unit can be relocated to sites rich in agricultural and forest residues, serving as a practical biomass combined heat and power plant and waste-to-energy power station. It is a cost-effective used waste combustion power plant that converts crop and wood scraps into usable energy, far more budget-friendly than brand-new construction. Many industrial investors prefer this used biomass cogeneration unit because it shortens project cycles and reduces upfront capital investment, without sacrificing stable output performance. Buyers can skip lengthy new equipment manufacturing cycles and launch their energy supply plan much sooner.

This used biomass cogeneration unit was formally shut down and hermetically sealed in 2025. All high-voltage power equipment and low voltage power equipment inside this used biomass cogeneration unit received energized anti-corrosion preservation. Every mechanical and electrical component of this used biomass cogeneration unit remains intact, free from aging damage. Buyers are welcome to carry out site inspection before power plant refurbishment and power plant commissioning. We supply full steam turbine spare parts for the extraction steam turbine and turbo generator of this used biomass cogeneration unit. The package includes a complete used turbo generator set, different from incomplete dismantled equipment on the market. Full auxiliary accessories come together with this used biomass cogeneration unit to cut the workload of on-site reassembly and debugging. All operation logs and maintenance records are retained, which greatly helps technical teams evaluate status and formulate the refurbishment plan for this used biomass cogeneration unit. Our technical team can provide remote guidance and on-site service support to guarantee smooth restart after relocation.

The core heating equipment of this used biomass cogeneration unit is the HX75/9.81-Ⅳ2 CFB boiler. This used CFB boiler, also classified as a biomass fired steam boiler, reaches a rated evaporation of 75 t/h, 9.81 MPa pressure and 540 ℃ steam temperature, with thermal efficiency above 90%. This CFB boiler boasts strong fuel adaptability, which can process high-moisture and high-ash biomass feedstock. Supporting the CFB boiler are a full RO water treatment system, power plant deaerator and steam condenser, which together create a stable closed water circulation loop. This CFB boiler configuration is widely adopted for agricultural residue power plant and forest waste power plant projects, guaranteeing continuous combustion and low emission output for the whole used biomass cogeneration unit. Its feeding, fluidization and dust removal subsystems remain complete, so the CFB boiler can maintain clean and steady combustion after restart, complying with mainstream environmental discharge standards.

Power generation of this used biomass cogeneration unit relies on its extraction steam turbine and turbo generator. The extraction steam turbine is Qingdao Jieneng C15-8.83/0.981, manufactured in 2018 with rated capacity of 15 MW. This extraction steam turbine can steadily supply 10 t/h industrial steam at 0.981 MPa extraction pressure, running at 3000 r/min. Besides this extraction steam turbine, we can also provide back pressure steam turbine and condensing steam turbine as alternatives according to customer demands. Paired with the extraction steam turbine is the QFw-15-2 alternator, forming a qualified 15MW steam turbine generator and extraction turbine generator package. This used power generation unit works steadily with low failure rates and serves as the turbo generator core of the used biomass cogeneration unit. Its excitation and cooling systems are well preserved to support long-time continuous operation under variable working conditions to match changing factory heat and power demand.

The supporting fuel processing system of this used biomass cogeneration unit is a WD-series biomass fuel crushing system, also known as biomass fuel crushing unit, with 20–40 t/h processing capacity. This biomass fuel crushing system crushes eucalyptus scraps, straw and forest residues into qualified particles for the CFB boiler. The system tolerates feed moisture up to 40%, greatly lowering raw material procurement cost for this used biomass cogeneration unit. The whole biomass cogeneration system of this used biomass cogeneration unit is designed for industrial steam supply plant scenarios. As a biomass renewable energy plant, it turns waste biomass resources into stable heat and power output. After simple debugging and commissioning, this used biomass cogeneration unit can be put into continuous, stable operation for long-term commercial use. It helps factories realize self-supply of power and process steam, cut energy purchase costs and meet local environmental policies for biomass utilization. This sustainable solution brings dual benefits of economic saving and carbon reduction for enterprise users.
