Model CBEX
Using advanced engineering methods, design engineers designed the CBEX to optimize every component of the boiler, including the burner, the furnace, and the tubes, in order to provide optimally balanced heat release zones and minimizing thermal stresses in the boiler. Extended heat transfer tubes only found in EX systems uses Computational Fluid Dynamics (CFD) calculations to optimize the geometry of the tube and increase heat transfer by 85%. The result of the advanced heat transfer design is higher efficiency in a smaller footprint. Reduce fuel use with the optional stack economizer by recovering waste heat from flue gases and using it to preheat boiler feedwater.

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.
