Velox Boiler - its components and working

Flue gases pass from the fire tubes near the bottom of combustion chamber. Thsese fire tubes are surrounded by the evaporator water tubes. When the water enters the evaporating tube at high speed, the heat form the gases are transferred at very high rate due to high speed of water and gas. After that mixture of water and steam is formed which
