The CBA Instanvap model is a horizontal, three-pass fire tube hot water and superheated water generator with a central, interior furnace that ensures maximum heating capacity.
Combustion occurs and is completed in the furnace which is completely surrounded and cooled by the boiler water. The exhaust fumes travel back through the furnace itself before entering the bundle of tubes to make maximum use of the heat and finally being vented into the atmosphere via the smokestack.
This reverse flame boiler has a wet chamber completely surrounded and cooled by water. Fire-proof materials are not required on the back, resulting in higher performance and lower costs and maintenance.
The boiler has a manhole at the top to enable the inspections and cleaning tasks necessary to keep the inside of the boiler in good condition.
At the front and back of the boiler there are hatches for access to the furnace gas tubes, fastened by screws designed not to seize up due to the temperature. Once the hatch is removed, it is held in place by swivel hinges. This makes inspections and any necessary cleaning quick and easy.
The CBA Instanvap is a robust, compact hot water generator supplied as a single package mounted on a solid bedplate for fast assembly and start-up.
To start the boiler, all that is needed is for the water, water pipeline and fuel tubes to be connected and the control panel to be cabled.
