Abstract:
This study & research work focuses on the design, Installation & optimisation of a 16 Ton capacity of Bogie Hearth Furnace used for MS round plate heat treatment for forgings of dish end of pressure vessel that is fired by LDO / Diesel as a fuel. The furnace may be run with PNG / LPG as an alternative fuel by making small changes in combustion system only. The furnace has an overall combustion Volume of 44.4 m³. It is fitted with a chimney to allow for the escape of combustion flue gases. The combustion air blower discharge air into the furnace at the rate of 1400 m³/hr with an air fuel ratio 11:1. This furnace was designed to consume 100 litters of LDO per Hour fuel with a rating of 40000 BTU / liter which is required to raise the temperature of 16 Ton MS round plate to 1050ºC. These MS plates are then forged in the press to manufacture the dish end of pressure vessel. The theoretical efficiency of the furnace is considered to be 30% for design calculations.
