Blog - HOW TO CALCULATE NATURAL GAS CONSUMPTION

Many applications for natural gas involve the heating of air or water. This section has some quick estimating formulas to calculate gas flows. With natural gas use on the increase we suspect that many applications for thermal energy using other fuels, steam or hot water might become candidates for conversion to natural gas.

Water Handbook - Boiler Blowdown Control | SUEZ

There are many mechanical factors that can affect the blowdown control limits, including boiler design, rating, water level, load characteristics, and type of fuel. In some cases, the blowdown control limits for a particular system may be determined by operating experience, equipment inspections, or steam purity testing rather than ASME or ABMA

Boiler Efficiency - an overview | ScienceDirect Topics

From Example 8.2, the existing boiler has an excess O 2 of 6% and an overall boiler thermal efficiency of about 78% (i.e., η s t d = 0.78). After the boiler tune-up, the excess O 2 is 3%. Using the monograph of Fig. 8.12, the new boiler efficiency can be determined from the flue gas temperature (343°C or 650°F) and the excess O 2 (3%).
