“…The need of combustion pressure had been satisfied by adjusting the back pressure, valve position and air flow at the exit portion of exhaust. The rise in compression air flow correspondingly increases the combustion chamber pressure after adjusting the back pressure and valve position (Park et al , 2018).…”

“…The carbon monoxide emission in current study remains constant at 10 ppm due to homogenous mixing of fuel and air with enhanced turbulent potency and cross flow velocity is affected by jet, proper dilution of nitrogen in the fuel effectively reduces the flame temperature. The nitrous oxide emissions in the study had been observed by chemi-luminescence photos obtained from the flame windows (Park et al , 2018). The exhaust emission based on variable pressure in the combustion chamber had been depicted in the Table 2 by Park.…”

Purpose The rise in demand and high utilization of fuel causes severe environmental threat for the nations on the globe. Rapid burning potential of hydrogen produces enormous amount of thrust, and it is mainly owing to wide flame range and less onset of ignition. Design/methodology/approach The significant contribution of hydrogen as fuel has been explored by several researchers around the globe recently to use in aviation sector owing to its eco-friendly nature. Hydrogen is a safe and clean fuel, and it can be generated from several sources. The effects of addition on hydrogen on gas turbine on combustion characteristics and emission concentration level on atmosphere have been reviewed in this paper. Findings Incorporation of hydrogen is effective reducing nitrous oxide emission, high calorific value and flame less combustion. Addition of hydrogen to higher proportions enhances the combustion performance, minimizing the setbacks of conventional fuel and meets the specified standards on emission. Originality/value From the literature review, the comparative study on hydrogen with other fuel is explained. This paper concludes that addition of hydrogen in fuel enhances the performance of combustion on gas turbine engine along with significant reduction in emission levels.

“…Wobbe and Weaver applied different historical parameters and specific indexes for the determination of fuel interchangeability. Park et al [4] used another approach. They used the model of the combustion plant for an evaluation of interchangeability of different types of fossil fuels, including synthesis gas from the coal gasification, steel gases, and blast furnace gas (BFG).…”

Exchangeability means the possibility of the fuel changing, with conservation of the required energy and environmental criteria. The assessment of fuel exchangeability should be realized by a suitable method, which must reliably present the possibility of the exchangeability of fuels, or reject it. In the presented paper, research on the exchangeability of solid fuels in the field of heating production is surveyed by the case study. Based on the available published knowledge from previous studies on fuel exchangeability, the statistical method was chosen for evaluation. The application of this method is useful. For example, by evaluating the exchangeability of natural gas, the manuscript will describe its application for the field of solid fuels in heat production. The research evaluated and analyzed the sample of 12 fuels. For each fuel sample, 35 gas attributes were measured, which were classified into separate flue gas attribute groups: ash content, combustion heat, heating capacity, sulfur content, combustible content, water content, emission factor, carbon content, hydrogen content, and oxygen content. Attributes of flues were evaluated and grouped according to the fuel properties—ash content and combustion heat, sulphur content, water content, emission factor, carbon content, hydrogen content, nitrogen content, oxygen content, and combustible content.

“…Park and Kim detected that H2O and CO2 dilutions are more effective than N2 to reduce NOx emissions [7]. Parka et al concluded the increased pressure raises NOx emissions and fuel side N2 dilution reduces NOx for coal based synthesis gas [8]. Williams et al found oxygen up to 22% in CO2 is beneficial to decrease NOx [9].…”

One of the main methods to decrease NO emission during the combustion of gases is the use of diluents. This study is interested in the effects of CO2, N2, and H2O dilutions in the adiabatic, turbulent, partially premixed combustion of synthesis gas. The amounts of NO emissions are computationally determined. The results show that NO maximizes at 1.39 of equivalence ratio under humid burning air conditions. The best reductive effect on NO emissions indicates H2O dilution followed by CO2 and N2. The increase in the dilution rates gradationally reduces NO. The rising pressure enhances NO emissions with/without diluters. The increasing inlet air and premixed mixture temperatures raises NO.
