The construction of this vertical fire tube boiler was carried out both at the industrial center and Mechanical Engineering workshop of the Institute of Management and Technology (IMT), Enugu.
The boiler contains 2 steam tubes at triangular pitch which are enclosed in a shell. Water is introduced through the shell. When the burner is put on, the products of combustion — excess oxygen, nitrogen and carbondioxide pass through the tubes at a high temperature and then heats the surrounding water, as a result, steam is generated.
It has a capacity of 20,000cm3 of water and can produce 0.05kg of steam per hour. It can be used widely for the generation of stem for laboratory uses and by small scale industries.
The materials used were mainly mild steel. About 10 electrodes were used for the welding and care was taken to ensure strong welding, although it is a low pressure boiler.
The top sheet plato is 0.0125cm thick. The tube bundles are galvanized tubes. Details of the engineering and working drawings are shown. The construction of this boiler did not follow any code.
The cost of the project is N12,000.
