Modifying steam power plants to lower emissions
The global pursuit of the energy transition has generated strong demand for low-carbon and renewable fuel. Yet, thermal power plants still play an important role in maintaining stability of power supplies in many countries around the world. The environmental impact of thermal power plants must therefore be reduced, and Mitsubishi Power has a variety of solutions to do so, including biomass- and ammonia-firing technology as well as solutions to convert existing coal or oil-fired power plants to natural gas.
Making power plants cleaner
By converting to natural gas, CO₂ emissions per kWh will be reduced by 40% compared to coal firing and 30% to oil firing. As natural gas has lower nitrogen content, significant NOx reduction (compared to coal firing) can be achieved with the installation of our low-NOx burner. Furthermore, as natural gas has lower sulfur and ash content, SOx and ash emission will reach nearby zero.
Natural gas’ higher ramping rate and better ignition quality also enable greater flexibility and help decrease minimum load on operation, making natural gas-fired power systems more compatible with renewable energy.
