Control system and method for biomass power plant

A method for controlling operation of a power plant system, the power plant system comprising at least a gasifier, a boiler, an induced draft fan, and a baghouse;

• the gasifier configured to receive input feed including biomass as fuel to produce exhaust gas;
• the boiler having a flame for igniting the exhaust gas received from the gasifier and for providing power, and a measurement device associated therewith configured to measure a temperature of the flame of the boiler and to determine loss of flame based on the temperature;
• the baghouse configured to receive exhaust gas from at least the boiler to remove particulates therefrom;
• and the induced draft fan configured to control the production rate of energy and to run at a predetermined speed to draw filtered exhaust gas from the baghouse for output via an exhaust system;
• and a controller in communication with the power plant system configured to implement the method after detecting loss of flame in the boiler using the measurement device, the method comprising:
• implementing a first stage sequence in response to the detecting the loss of flame in the boiler comprising:
• automatically bypassing the baghouse;
• automatically decreasing the speed of the induced draft fan;
• and
• determining if the flame of the boiler is reestablished.
