Hot Water Boilers – ICAQ

The ICAVI hot water boiler project aims to meet the market demand for energy generating units, with high thermal efficiency and low operating cost, having as basic characteristics the construction of the body of two or three passes in the gas circuit, with expanded tubes , burning of fuel through a reciprocating grill, with a furnace and post-burning chamber lined with refractory bricks, in order to ensure complete combustion.

The walls of the ICAVI boilers are all built with panels of finned tubes, which makes the wall highly resistant and shielded against gas leakage and external air intake.

In the internal part of the furnace and post-firing walls, refractory bricks are installed with a perfect fit on the finned walls, thus allowing a greater transfer of heat from the refractory to the tubes. The same refractories fit together, creating resistance when applied and anchoring them to the finned walls.

Acceptance of fuels with a high degree of humidity, variations in fuel granulometry and due to the large mass of fuel on the grill, stability in combustion and boiler load.

The design of the heat exchange areas had the objective of providing sufficient safety margins to meet the production peaks, to compensate for the thermal resistance caused by normal soot films that will eventually adhere to the tubes, guaranteeing the production of thermal energy and the expected efficiency throughout the operation period.

The convection section was calculated with an adequate speed so as not to allow sedimentation of the solid particles possibly contained in the gas, but at levels that ensure no risk of erosion at the entrance of the gases.
