BIOMASS CO-FIRING 1.0 System Description Figure 1. Biomass co-firing retrofit schematic for a pulverized coal boiler system. Co-firing is the simultaneous combustion of different fuels in the same boiler. Many coal- and oil-fired boilers at power stations have been retrofitted to permit multi-fuel flexibility.
The company plans to build a heating supply plant in South Korea, including two sets 12MW, 1.6MPa coal fired boilers to generate hot water. However, due to the low heating value of coal (2500kcal/h), our design engineer makes adjustment over current CFB hot water boiler. Main adjustment is over the heating surface and cyclone separator.
Any facility installing a biomass energy system should select a high-efficiency boiler with an automated feeding system. The size of the system should be based on the facil-ity’s heat energy requirements. The boiler should have primary and second-ary, and/or tertiary air systems linked to oxygen sensors in the flue, detecting oxygen

Coal CFB Boiler uses bed material (such as silica sand) to support the combustion of coal around 900°C to generate heat. Steam produced inside the combustor can be used for power generation in steam turbine. Coal CFB Boiler can suit varying particle size (1-10mm) and varying fuel quality (from anthracite to lignite, petroleum coke).
1. High calorific value of fuel: biomass particles have high calorific value, and the calorific value is about 3,900-4800kcal /kg. 2. High purity fuel: the biomass particle fuel has high purity and does not contain any other impurities that will consume heat instead of heating, which will directly reduce the cost for the enterprise.
