can firetube boiler react quickly to load changes

Boiler plant and auxiliaries - ScienceDirect

This chapter discusses boiler plant and auxiliaries. The advantages of sectional boilers lie in the relatively small component part involved. As the life of a central-heating boiler is usually less than that of the building that it serves, the question of boiler replacement must be considered at an early stage in the design of a building and its services.

The rewards often are realized in higher system efficiencies and fewer forced outages. An older boiler often can be made 1 or 2 percent more efficient by retrofitting a microprocessor control system for the pneumatic or analog-type controls already in place. Cost recovery can occur quickly when fuel budgets range in the millions of dollars per

If the boiler is operated below 50% load, more air is required to burn the fuel which increases the sensible heat loss. It is always better to run less number of boiler at high load than more number at low load. Pro Tips: •Highest efficiency of boiler can be achieved at 2/3rd of the full load •Avoid running the boiler at below 25% load as
