How to compare Natural Gas Boiler and Coal Boilers?

Apr 05, 2017 · There are not many commercial or industrial coal fired boilers left, but where they exist the load is substantial and the equivalent gas energy usage is measured in the millions of MCF per year. These boilers are typically at least 50,000 lbs of steam per hour (1,000 HP) and larger. They are typically located at very large industrial facilities, paper mills, large food processors and electric

Boiler Operations That Affect Efficiency (Part 2)

The total combustible burned will be 16,975 - 2396 = 14,579, and the evaporation from and at 212 degrees per pound of combustible will be 165,516 ÷ 14,579 = 11.35 pounds. Hence, the efficiency based on combustible from ( 32) will be (11.35 × 97.04) ÷ 15,359 = 71.71.

Boiler Operations That Affect Efficiency. (Excerpted from Steam/its generation and use, 42nd edition) In its simplest form, efficiency is the ratio of energy output to energy input, expressed as a percentage. To optimize efficiency, therefore, it is important to minimize input (fuel being a major source) and maximize output (steam production).
