Boiler Operation Maintenance & Safety Study Guide

Boiler Use • A boiler may be classified as either a steam boiler or hot water boiler. The vessels are the same and the boiler trim (controls & piping) determine the use of the vessel. A steam boiler must maintain a water level covering the top of the heating (tube) surfaces while leaving room for steam production.

Calorific Value For Natural Gas & MFO - CR4

2010-9-29 · The CV of NG is slightly lower on a mass basis, but all that means is the burner has to pass slightly more gas to compensate and achieve the same firing rate. The products of combustion of NG contain more water vapour than MFO so the flue loss tends to be slightly higher at normal boiler flue exit temperatures as a result, all other things

Fossil Fuel Fired Industrial Boilers - Background

The three major boiler designs — watertube, firetube, and cast iron -- are each manufactured to meet specific application and site requirements. Unit size, design steam pressure and temperature all depend on the application. Each of these boiler types may burn coal, oil, or gas and are increasingly being designed to burn more than one fuel type.
