Abstract

Two biggest problems in present Indian pulverized coal combustion (PCC) power plants are that large capacity of PCC plants has reached retirement due to age limit and huge coal import from outside countries. Increasing the utilization of circulating fluidized bed combustion (CFBC) technology in India is the best solution for renovating old PCC boilers to extend their life to 20–25 years and reducing coal import by increasing the utilization of local low-grade coals in effective manner. Even though CFBC technology is economically sound, technically feasible and environmentally friendly than PCC technology, CFBC technology utilization in India is still in the nascent stage. To increase the utilization of CFBC technology in India, more design models are needed to come out on Indian low-grade fuels such as Indian lignite and high ash coal for predicting thermal and environmental performance, analysing design and optimizing processes in operation at wider range of operating parameters. In this paper, a CFBC boiler design modelling which is developed by programming code of visual basics for applications (VBA) software is explained. To check the accuracy, the design methodology is applied to validate the practical data of different CFBC units on various aspects such as thermal performance model (boiler efficiency, flow rates), hydrodynamic model (solids volume fraction), heat transfer model (water wall heat transfer coefficient) and sulphur capture model (SO₂ emissions). The design procedure which is applied for validation process gives satisfactory results on different aspects, and the qualitative agreement is found between predicted values and actual measurements.
