Or, the burner arrangement may not be able to sustain the parameters used to calculate the efficiency over the life of the boiler. It is difficult to verify efficiency after the boiler is installed without costly test procedures. However, techniques are available to prove efficiency before you invest by reviewing the basic boiler design criteria and data used to calculate the efficiency value. Efficiency is broken into five segments that allow boiler alternatives to be more accurately evaluated and compared. Comparing key design features also helps determine potential boiler efficiency more accurately.
Initial cost is the smallest part of an overall boiler investment.
Understanding boiler operating cost is the key to maximizing the investment year in and year out. The following example compares four alternatives and their efficiencies. On the basis of this information, there is no way to tell. Each type represents something different. Typically, thermal efficiency reflects how well the boiler vessel transfers heat.
