Consider a 50,000 pound-per-hour process boiler with a combustion efficiency of 79% (E1). The boiler annually consumes 500,000 million Btu (MMBtu) of natural gas. At a price of $8.00/MMBtu, the annual fuel cost is $4 million. What are the savings from an energy-efficient burner that improves combustion efficiency by 1%, 2%, or 3%?
cy boiler with an economizer. If a steam boiler does not have an economizer, it can be retrofitted in the field. According to Kenneth McKelvy of Babcock and Wilcox, the rule of thumb is every 40°F (22°C)decrease in stack temperature equates to a 1% increase in boiler effi-ciency. A typical economizer can increase boiler efficiency by 4% to 6%.

Saving energy - reducing costs - protecting the environment Energy, cost and emission-saving solutions for shell steam boiler systems The life expectancy of a boiler system is between 20 and 40 years. Typical eﬃciency gains achieved by replacing or modernising old systems is between 10 and 30 percent, depending on the initial situation.
Boiler Energy Saving Tips. To ensure that the boiler is operating efficiently, TLV recommends that you do the following: Set a standard maximum percentage of excess combustion air. Set suitable minimum levels of fuel quality and viscosity to improve the efficiency of fuel combustion. Regularly measure and record fuel usage, exhaust gas
against hot boiler blowdown. The use of steam to preheat boiler feedwater was common when energy was cheap, but using surplus process heat instead (from below the "process pinch" temperature) represents a significant opportunity for improved cycle efficiency. Overall boiler efficiency becomes
Saving energy helps you save money on utility bills and protect the climate by reducing greenhouse gas emissions. ENERGY STAR certified commercial boilers have a thermal efficiency of ≥ 94.0% and a turndown ratio of 5:1. Thermal efficiency is the ratio of the heat energy (Btu/hr) absorbed by the water to the heat energy available in the fuel
The total economic loss is $2394/h if the unit cost of high pressure steam is taken as $33/Gcal. Effect of stack gas temperature on boiler efficiency. Stack gas temperature is a parameter that effects the efficiency of a steam boiler and needs to be traced closely.
