  • Boiler Efficiency and Steam Quality: The Challenge of

    "Operate the boiler at its maximum design pressure" is a common saying among boiler designers. But too often, this rule is not followed when energy cost reductions are needed. During periods of low steam demand, or when all the use points require pressure-reducing stations, boilers are often operated at substantially less than design pressure.Learn More

  • Use Feedwater Economizers for Waste Heat Recovery

    natural gas-fired boiler load of 50 MMBtu/hr is read from the table (above) as 4.6 MMBtu/hr. Annual Savings = (4.6 MMBtu/hr x $8.00/MMBtu x 8,400 hr/yr)/0.80 = $386,400 Suggested Actions Determine the stack temperature after the boiler has been tuned to manufacturer's specifications. The boiler should be operating at close-to-optimum excess Learn More

  • Boiler Efficiency | How to balance steam loads efficiently

    Aug 26, 2011 · The first step is to understand the load-versus-efficiency characteristics of a typical package boiler. Table 1 shows performance variation as a function of load. The boiler with an economizer generates 100,000 lb/h of saturated steam at 400 psig using natural gas. At load, the exit gas temperature is 320 °F. Excess air is 15%.Learn More

  • Efficiency factors in natural gas fired steam boilers

    According to Figure 3, boiler efficiency increases with increased usage of boiler load. When this trend is examined, an increase of 6% in boiler load increases efficiency by 3%. The boilers shown in Figure 2 have 350 t/h capacity. High pressure steam is produced at 38 bar and 440°C which supplies 4130 Gcal/h of thermal power. However, the average usage of this capacity is 205.4 t/h which corresponds to 2423 …Learn More
