The study was developed inside an integrated steel mill, located in Rio de Janeiro city, aiming to analyse the technical-economic feasibility of installing a new inlet air refrigeration system for the gas turbines. The technologies applied for such purpose are named Turbine Inlet Air Cooling (TIAC) technologies. The power plant utilizes High Fogging and Evaporative Cooling methods for reducing the compressor’s inlet air temperature, however, the ambient climate condition hampers the turbine’s power output when considering its design operation values. Hence, this study was proposed to analyse the installation of an additional cooling system. The abovementioned power plant has two heavy-duty gas turbines and one steam turbine, connected in a combined cycle configuration. The cycle nominal power generation capacity is 450 MW with each of the gas turbines responsible for 90 MW. The gas turbines operate with steelwork gases, mainly blast furnace gas (BFG), and natural gas. The plant has its own weather station, which provided significant and precise data regarding the local climate conditions over the year of 2017. An in-house computer model was created to simulate the gas turbine power generation and fuel consumption considering both cases: with the proposed TIAC system and without it, allowing the evaluation of the power output increase due to the new refrigeration system. The results point out for improvements of 4.22% on the power output, corresponding to the electricity demand of approximately 32960 Brazilian homes per month or yearly earnings of 3.92 million USD.

Blast furnace gas (BFG) is an important residual fuel gas formed in the blast furnaces. Its utilization for heating and power generation improves the overall energy efficiency of steel industry. In this work, the premixed combustion of BFG and air combustion was investigated with particular emphasis on the variations in composition of BFG. Fundamental properties of the premixed laminar flame and chemical reactions were estimated with the help of the USC Mech. II comprehensive kinetic model developed for the combustion of CO/H 2 /C 1 −C 4 mixtures. Predictions of the kinetic model were validated on a large set of experimental data for BFG−air flames and one syngas−air dataset covering ϕ = 0.7−1.5, T = 298−393 K, P = 0.1 MPa, and multiple compositions, without requiring ad hoc changes in the default rate parameters. Flame structure and flame properties were analyzed with the help of reaction path analysis, rate of production analysis, and sensitivity analysis. Results of these analyses showed that H 2 chemistry influences the propagation of stable BFG−air flames. A detailed uncertainty analysis was carried out to reveal the significant effects of compositional variations on the flame temperature and burning velocity of a well-mixed BFG−air mixture. The analysis showed variations in the range 4.2−22.5 cm/s and 1195−1731 K for laminar burning velocity and flame temperature, respectively. Correlations were developed using the uncertainty analysis showing that H 2 affects the burning velocity and CO affects the flame temperature. The uncertainty analysis could be a useful tool to determine the operating conditions for a well-mixed fuel-flexible combustor.Article pubs.acs.org/IECR

“…The results show the potential to improve the blow-off limit and characteristics are reported for hydrogen-methane fuel blends. With the knowledge of the formation and use of blast furnace gas, Pugh et al [22] conduct a case study to analyse the impact of sampling location on fuel properties and performance.…”
