The following points may be kept in view while selecting a boiler:

  • The shifting and evaluating the competing claims of different manufacturers is no longer a layman’s job. It should be entrusted to a consultant.
  • As of today, boilers are in buyers market. Only a decade ago they were in sellers market.
  • Because a boiler is offered by a reputed firm it needs not to necessarily be good and because it is offered by a minor company just getting into business, it need not be bad.

When writing to the boiler manufacturers, the following information should be furnished to them:

  • Lowest ambient temperature likely to be reached during a year at the proposed place of operation.
  • Elevation of the place above MSL
  • Maximum working pressure
  • Maximum steam demand at the working pressure of the boiler.
  • Fuel to be used and its analysis report.
  • Whether the load on the boiler is likely to be steady or fluctuating and if fluctuating, then between what limits?
  • Analysis of the raw water to be used in the boiler after treatment.
  • In case of solid fuel fired boilers, whether mechanical firing is preferred.
  • In the event of any proposed standardization of both the HPs & the maker of electric motors that fact should be intimated.

The boiler manufacturer should be requested to include the following information in the quotation he sends

  • Gross thermal Efficiency of boiler with the type of fuel cited
  • Accessories included
  • Quality of steam-dryness fraction
  • Flue gas temperature
  • Grate area(for solid fuel fired boilers)
  • Expected  evaporation(kg of steam at working pressure/kg of fuel)
  • Heating surface area
  • Delivery Period
  • Overall dimension of the boiler
  • Quality of boiler feed water required?
  • Weight of empty boiler & weight when water is at its full level
