ABSTRACT

The efficiency of a boiler the ratio of heat utilized in producing steam and heat liberated in the furnace, but the heat liberated in the furnace is always greater than heat utilized in the boiler ,the differences that exist between these forms of  heat is known as the heat losses in the boiler .This paper analyses the various heat losses as it affects the efficiency of the fire tube boiler located  at the department of Mechanical Engineering, Kaduna Polytechnic. Emphasis was made on the reason for these losses and ways to minimize it.
