combustion process of hot water boilers that use fuel oil and natural gas, as a function of the boiler load. The paper focuses on parameters that should be controlled in flue gas and determination of their specific limits in order to have combustion process with the highest coefficient of utilization while
The main parameters that affect a steam boiler's efficiency are boiler load, combustion air, stack gas temperature, radiant heat loss, and acid dew point. In this article, natural gas fired conventional steam boilers are evaluated and potential savings are determined in the power plant of Tüpraş İzmir refinery.
corresponding amount of natural gas to thermal or process heat every hour. This would be sufﬁcient to heat more than 2 000 houses. Because of the huge volume of water and the multi-stage lead-through of the ﬂue gases, these boilers are also called three-pass shell boilers.
An Approach towards Efficient Operation of Boilers
Combustion of standard fossil fuels (natural gas and ASTM Grade Oil) in commercial and industrial boilers results in the following nine emissions; carbon dioxide, nitrogen, oxygen, water, carbon monoxide, nitrogen oxide, sulfur oxides, volatile organic compounds, and particulate matter.

The emissions from natural gas-fired boilers and furnaces include nitrogen oxides (NOx), carbon monoxide (CO), and carbon dioxide (CO 2 ), methane (CH 4 ), nitrous oxide (N 2 O), volatile organic compounds (VOCs), trace amounts of sulfur dioxide (SO 2 ), and particulate matter (PM).
A natural gas boiler further increases the water temperature in case of thermal demand peaks. The electricity and heating demand profiles, the delivery temperature (constant at 80°C), return temperature and DHN water flow rate derive from operational data of a real plant.
