Industrial Furnace - an overview | ScienceDirect Topics
Modern condensing natural gas boilers can reach annual net efficiencies of about 102%, modern oil boilers about 98%. (The ratio refers to the lower heating value of the fuel therefore efficiencies of more than are possible for condensing boilers.) High efficiency reduces the CO 2 …

Thermal Oil - an overview | ScienceDirect Topics
The thermal oil boiler (Figs. 15.12 and 15.13) transfers the heat content in the combustion gas to the thermal oil.The temperature of the combustion gas at the inlet of the thermal oil boiler is normally about 950°C. The outlet temperature of the thermal oil directed to the ORC can rise up to 320°C, due to the use of high quality synthetic oil.

Thermal Performance and Efficiency of a Mineral Oil
Boiler efficiency (%) = 100 (heat exported by the fluid (water, steam ..) / heat provided by the fuel) (1) Heat Exported from the Boiler to the Fluid If a fluid like water is used to transfer heat from the boiler - the heat transfer can be expressed as: q = (m / t) cp dT (2) where q = heat transfer (kJ/s, kW) m / t = mass flow (kg/s) m = mass (kg)

Boiler Scale and Corrosion Inhibitors | Watertech of
Corrosion inhibitors help to reduce equipment repair costs, improve water quality, conserve energy, lessen waste, and improve safety. Polymer treatments inhibit scale and deposits by working to disperse solids that form in boilers. Scale inhibitors help boiler water maintain pH levels between 10 and 11.

Determining & Testing Boiler Efficiency for …
However, if the furnace's efficiency is 50 percent, then the actual heating value of fuel oil is 140,000 BTUs x 0.5 (efficiency) = 70,000 BTUs. In other words, when a gallon of oil is burned, 70,000 BTUs of heat is actually available to the user. Efficiency of a Furnace Click here to see the graph's tabular data

Once the mineral oil is used up, it can be mixed with fuel to be used in oil-fired boilers. Hence, the cost of disposing mineral oil is less and much easier than that of synthetic fluids. There is much less odour with mineral oils than with synthetic liquids. If a spill occurs, it doesn't require comprehensive reporting as compared to
