Doosan Lentjes Discusses Supercritical CFB Boilers at POWER-GEN Africa

During the POWER-GEN Africa, Doosan Lentjes will speak about supercritical circulating fluidised bed (CFB) boiler solutions designed for low-grade local fuel types.

The event will take place from 14-16 May in Cape Town, South Africa.

Supercritical CFB boilers help to increase the efficiency of steam and power generation units, whilst, at the same time, reducing their negative environmental impact.

By operating according to the proven CFB principle, the supercritical CFB units provide unchanged optimum conditions for the exchange between gas and solids, ensuring excellent ash burnout and heat transfer. This principle ensures maximum fuel flexibility and, thus, enables the efficient combustion of various fuel types, especially those with demanding combustion properties such as high ash contents. At the same time, it also makes applications for biomass co-firing possible, which further increase the environmental balance of the power generation process.

Compared to subcritical applications, supercritical units operate with enhanced temperature and pressure parameters, allowing the maximum performance potential of the steam generated to be utilized. This reduces the consumption of coal and, thus, the emissions, especially CO2.

Against the background of its positive characteristics for increasing the sustainability of steam and power generation, the World Bank has announced that it will finance only this type of investment. Subcritical targets will not be further considered. 

In Cape Town, Doosan Lentjes will outline the certain design strategy for supercritical units, while, at the same time, addressing the impact of biomass co-firing on both boiler and equipment. Scheduled on 14 May, the speech will be part of the POWERGEN Africa Knowledge Hub
