Introduction

The boiler unit consumes a significant portion of a building's energy. Large gains can be made in this area with relatively simple system modifications. This page will provide information to aid in the audit of a boiler unit.

General Boiler Information

There are a number of boiler types, all with advantages and disadvantages. The most common boiler types are listed below:

  • Fire Tube BoilerW
  • Water Tube BoilerW
  • Cast-Iron BoilerW

Within this general group, there are a number of sub-types, including:

Boiler Data

BoilerW Information required:

  • BTU Output (BTUW)
  • Maximum Load Efficiency
  • Service Area (volume, heating requirement) <-
  • Type of Fuel <-
  • Cost of Fuel
  • Type of Boiler Control (manual, automatic) <-
  • Auxiliary Equipment Used <-
  • End-Use Devices (specifically control methods)
  • Placement of Control devices (ie. temperature sensors) <-
  • Automated Control Schedules <-
  • Average Usage <-
  • Turndown Ratio
  • Boiler System Dampers
  • Steam Traps (if used)
  • EconomizerW (existence)

(Information)

Burner and Fan System

The burner and fan system of the boiler unit provides a means to increase efficiency. These units can sometimes be modified to include newer, more efficient components, however care must be taken to examine the boiler design to prevent unwanted results (heat transfer characteristics are important here). Information required:

  • Cleaning and Maintenance Schedule
  • Type of Burning Unit
  • Type of Fan Motors
