The thermal conductivity of an average boiler scale is 2.2 (W/m K) and that of complex silicate scales is 0.2–0.7 (W/m K). Since the furnace peak wall flux can be over 300 000 (W/m 2 ) it may readily be seen that a small thickness of scale can raise the metal temperature into the creep region, resulting in very expensive repairs.Get A Quote
On the front of the boiler is an external reversing chamber, which again reverses the flue gases and leads them to the end of the boiler in the 3rd smoke tube pass. Hot water boilers are normally completely filled with water during operation. Steam boilers on the other hand are only 3/4 filled with water; the upper quarter is the steam space.Get A Quote

Pulverised fuel burners may be classified as follows: 1. Long flame burners. 2. Turbulent burners. 3. Tangential burners. 4. Cyclone burners. Oil Burners: Principle of Oil Firing: The functions of an oil burner are to mix the fuel and air in proper proportion and to prepare the fuel for combustion. Fig. 12.14 shows the principle of oil firing.Get A Quote
