Boiler Introduction | CleanBoiler.org

In firetube boilers, the combustion gases pass inside boiler tubes, and heat is transferred to water on the shell side. Scotch marine boilers are the most common type of industrial firetube boiler. The Scotch marine boiler is an industry workhorse due to low initial cost, and advantages in efficiency and durability.

Modulation - Raypak

As shown, the primary energy efficiency advantage of modulation occurs at the low fire rates associated with light heating loads. It is appropriate to point out that a properly sized boiler system rarely operates at its design load. Typically a boiler system operates at less than 40% firing rate more than 60% of the time.

have inherently lower heat rates than smaller boilers. Figure 1 shows a plot developed in this effort from data in NEEDS v4.10 of boiler heat rate versus capacity for all pulverized coal or cyclone boilers. As shown, heat rate is highest for small boilers and lowest for large boilers, and this is worth examining further. 3. Facility age. 5

KEY COMPONENTS OF BOILERS | Boilers Guide

Boiler controls help produce hot water or steam in a regulated, efficient, and safe manner. Combustion and operating controls regulate the rate of fuel use to meet the demand. The main operating control monitors hot water temperature or steam pressure and sends a signal to control the firing rate, the rate at which fuel and air enters the burner.
