Chapter 14 Boilers - Pearson

A steam boiler is used to meet your high or low pressure steam system requirements while a hot water boiler is typically used to provide hydronic heat. Since these types of boilers have different usages, there are certain inputs that matter more when estimating the size of your boiler.

Plant Engineering | When to use electric steam boilers

Sep 06, 2001 · For oil fired boilers, the situation is similar — fuel prices vary by locale and supplier, and are prone to future increases. Table 1 assumes a price of $1.40/gal. and an energy content of 138,000 Btu/gal. Dividing that into the input of 1,338,000 Btu/hr (the same as the gas-fired boiler), the boiler is consuming 9.7 gal./hr.
