improving the efficiency of a high pressure steam boiler is to install an economizer on the boiler. Typically, on a high pressure water tube boiler, the efficiency improvement with an economizer is 2 to 4%, depending on firing rate. On a high pressure fire tube boiler, the improvement is 2 to 3.5%, depending on boiler size and firing rate.

Mayer et al. [48] described the use of a boiler for thermal fluid heating in a batch still; unsatisfactory operation resulted due to the cost of the thermal fluid, the insufficient heat transfer surface of the reboiler, the possibility of ethanol contamination by the thermal fluid and the extended time required to begin product withdrawal (2.5 h).

BOILER WATER TREATMENT INTRODUCTION A boiler is a closed vessel in which water under pressure is transformed into steam by the application of heat. In the boiler furnace, the chemical energy in the fuel is converted into heat, and it is the function of the boiler to transfer this heat to the contained water in the most efficient manner.

should be considered. Since boiler plants traditionally have a useful life of well over 25 years, replacement must be carefully studied. This paper is convergent on the diverse aspects of the operation of Boiler efficiently. Efficient operation of boiler is likely to play a very big role in following years to come.

Boilers are one of the most used units for both heat generation plants and industry systems. Their operation is subjected to different working loads and maintenance requirements. Exploitation experience points out critical boiler zones where failures and break downs typically occur. This paper analyzes critical zones in hot water fire-tube boiler.

In variable pressure operation, boiler pressure is varied to meet turbine requirements. This can significantly improve cycle efficiency when operating at low loads (15 to 40% of maximum continuous rating, or MCR). However, boiler response to turbine requirements is slower in this mode. When fast response is needed, pressure increments are used.

Thus in this paper an attempt is made to understand the way by which boilers can be used efficiently.

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.
