Validated methods for flue gas flow rate calculation wit

2012-2-9 · For a range of natural gas compositions, encompassing the proposed European fuel supply standard, exact calculations of the stoichiometric flue gas volume are compared with the empirical EN 12952-15 calculations. The level of agreement is again very good. Validation on fuel oil has been limited to light fuel oils fired in gas turbines and boilers.

Plant Engineering | When to use electric steam boile

2001-9-6 · 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.
