An established biomass combustion technology for all co-firing ratios

Mitsubishi Power's biomass combustion technology flexibly accommodates all co-firing ratios, not only in newly-built power plants, but also in existing ones. Through unique conversion programs for existing, coal-fired equipment, this technology makes it possible to switch to biomass combustion within a short period of time. In addition, through the core technology of pulverizers and burners that exhibit the same level of performance as coal-fired plants, it contributes to safe and secure plant operation, even after the conversion. Leveraging its deep experience in building new biomass facilities and converting old ones for biomass use, Mitsubishi Power provides one stop solution.

FEATURES

Conversion programs to effectively use existing equipment

Mitsubishi Power offers boiler conversion programs to achieve CO₂ emission reduction targets from biomass power generation. We can flexibly accommodate customers’ desired biomass co-firing ratios and propose the ideal combination of conversion costs, running costs, plant electricity capacity, and any other design considerations. In addition, we conduct detailed on-site surveys in order to achieve stable electricity supply and highly-efficient operations and can propose conversion plans that are optimal as seen from both economic and technical evaluations. Even if our customer have no clear plans, we are available to discuss your biomass utilization.

The use of biomass made possible with existing equipment and minimal construction

Mitsubishi Power's core technology of a coal/biomass dual-use system (pulverizes and burners) can be applied to make use of existing coal-fired equipment. Equipment can be converted with minimal construction, not only for biomass mixed-fuel combustion, but also for biomass-exclusive combustion. After conversion to biomass combustion, it is possible to switch between biomass combustion and coal combustion within a short period of time, to adapt to fuel availability.

Two types of high-performance burner with high combustion efficiency, even with biomass

Possessing both corner firing and opposed firing boiler technologies, Mitsubishi Power can respond to a customer’s every need. Due to our proprietary low NOx burner technology, both burner types can achieve the same high level of combustion efficiency and reliability with biomass as with coal. With its excellent ignition stability, it contributes to efficient NOx reduction in the flame and the optimization of O₂ concentration through control of secondary air.
