VELOX BOILER
Type :- High pressure, water tube, forced circulation steam boiler. Working principle : It's principle of working is “when the gas velocity exceed sonic velocity, the heat is transferred from the gas at a much higher rate than rates achieved with sub-sonic flow. The advantage of this theory is taken to effect the large heat transfer from a smaller surface area in this boiler ”. Construction & working : - VELOX boiler makes use of pressurised combustion . - The gas turbine drives the axial flow compressor, which raises the incoming air from atmosphere pressure to furnace pressure. - The combustion gases after heating the water and steam, flow through the gas turbine to the atmosphere . - The feed water after passing through the economiser is pumped by a water circulating pump to the tube evaporating section. - Steam separated in steam separating section flow through the superheater and form superheater its move to prime mover.
