“…There is still room to improve the efficiency of natural gas-burning equipment, thereby reducing greenhouse gas emissions [7]. The implementation of carbon dioxide capture technology in the process of natural gas combustion [8] and the use of carbon dioxide as a circulating medium [9] will reduce the carbon footprint of natural gas technology. Furthermore, gas boilers offer the advantage of integration with renewable energy sources to create hybrid systems [10].…”

The paper presents a cause-and-effect analysis of the failure of a 130 MWt gas-fired water boiler. The fault was a rupture of the helically finned tubes in the first rows of the second-stage water heater (ECO2). The high frequency of failures forced the boiler user to investigate their causes. The rapid drop in water flow in the ECO2 and the tightly finned pipes suggested that the permissible operating temperature of the steel used was exceeded. The only possible way to assess the working conditions was through a CFD simulation of the operation of the ECO2. Validated with the data acquisition system, the results show that the main reason for the failure was the overheating of the first rows of finned water heater pipes, regardless of the boiler load. The high heat flux value, exceeding 500,000 W/m2, and the increased flue gas temperature in front of the ECO2, almost reaching 900 °C, affected the appearance of the boiling film, limiting the cooling of the tube wall. Heat radiation and eddies behind the tubes significantly impacted the non-uniform temperature distribution, resulting in high pipe wall stress. By analyzing the service life of the first row of pipes based on the Larson–Miller parameter, it was concluded that the pipes would fail after only a few tens of hours.

“…In addition, although the concentration of CO 2 in the flue gases emitted from natural gas power plants is low, approximately 4−6 vol % of CO 2 , CCUS technology is being even asked to apply to the plants due to their increasing units. 2,3 Currently, the chemical CO 2 absorption process using alkanolamine-based solvents has been partially commercialized among the various CCUS technologies, and monoethanolamine (MEA) aqueous solution�the MEA concentration of which is approximately 30%�is the most representative and widely used solvent due to its efficiency, economy, and fast reaction with CO 2 . 4−7 Nevertheless, a lot of research has still been conducted to address the low economies of the systems and overcome some remaining technological hurdles of the process.…”

“…In particular, CCUS technology is expected to play a significant role in the giant CO 2 emission sector, such as coal-fired power plants, steel industry, and cement manufacturing. In addition, although the concentration of CO 2 in the flue gases emitted from natural gas power plants is low, approximately 4–6 vol % of CO 2 , CCUS technology is being even asked to apply to the plants due to their increasing units. , …”
