Cannon Boiler Works
Steam Accumulators
A steam accumulator is a pressure vessel (or tank) with internals and controls, that can reduce the fuel consumption, maintenance costs and increase the service life of your boiler by stabilizing the steam draw conditions, but it cannot make up for shortcomings in total boiler capacity. The accumulator acts as a flywheel or capacitor, storing energy for short periods until the process requires it.
Large load swings frequently cause boilers to shut down because the system thinks it won’t be able to meet short term steam demands. When this happens, personnel must get involved to rectify the disruption in operations which leads to higher maintenance costs. By incorporating a Steam Accumulator, you can ensure smooth boiler operations with lower maintenance costs.
