A Study on the Failure of AISI 304 Stainless Steel Tubes in a Gas Heater Unit

Abstract: This paper investigates a failure in convection section tubes of a gas heater unit in a petrochemical plant. Tubes are made of AISI 304 stainless steel. The failure is reported after 5 years of service at working temperature 500 °C. The failure is in the form of circumferential cracks in the vicinity of the weld. Various characterization techniques, including optical and electron microscopes as well as energy-dispersive X-ray spectroscopy (EDS), were used to study the failure. Results showed that that the damage has initiated in the heat affected zone (HAZ) area parallel to the weld/base metal interface. Cracks have propagated alongside grain boundaries, resulting in an intergranular fracture. The main cause of failure was concluded to be attributable to the grain boundary sensitization and intergranular grain boundary attack due to improper welding and long time exposure of tubes to high temperature. Possible mitigation strategies to minimize similar failures will be discussed.

Environmental impact assessments of heat pump–gas fired water heater hybrid system for space heating application

Abstract: Hybrid systems combining heat pump and gas heater can demonstrate the economic benefits, while their environmental performance is rarely investigated. In this paper, a comprehensive environmental performance investigation has been conducted to reveal the potential for emission reductions. A new environmental impact methodology has been built, and various influencing factors are evaluated. In respect of the climates, the hourly energy consumption emission first increases and then declines, which is the result of multiple effects from the weighting factors of fuel source emissions and each heating sector’s performance. Under the operation condition map for the current study, the effects of the target (final) water temperatures, electricity generation emission factor reduction, and price ratios are revealed to be the top 3 heaviest fluctuations for emissions for hourly system operation energy consumption, followed by each heating sector’s efficiency enhancements. The environmental impacts due to hourly system operation do not closely follow the hourly energy consumption profile for the effect of climate conditions and can be quite opposite when considering the effect of fuel source price ratios. In addition, the lifetime environmental performance has been examined for typical cities in China. In the cold region, such as Shenyang, the emission due to the natural gas contributor shares more than 46% of the total emissions. For warm cities (Shanghai, Wuhan, and Chengdu), the emission of the natural gas is only responsible for ~ 9% or even less of the total emissions. A switch from R410A (GWP100:1924) to R452B (GWP100:675) can also lead to ~ 11% emission total reductions for city of Shanghai, Wuhan, and Chengdu. It is anticipated that the viewpoints and insights from this study can be beneficial for the engineers, policymakers, scholars, public, and manufactures to maintaining the maximum sustainability and economic benefits.

A review of heat recovery possibility in flue gases discharge system of gas radiant heaters

Abstract: Heating of large-cubage buildings accounts for significant share of energy consumption. The radiant heating system using gas heaters is a common solution for large-cubage halls and is considered to be energy efficient. There is a possibility of additional heat energy recovery from the flue gases of gas radiant heaters because new solutions were introduced to the market. Furthermore heat recovery consists the most promising solution and develop during the recent years rapidly. On the other hand, few works have been dedicated to heat recovery from exhaust gas but none of them consider exhaust gas from radiant heaters. Exhaust gas temperature depends on the type and efficiency of the gas heater. The selection of both the type of radiant heaters and the heat recovery system requires many factors to be taken into account. This study consider possibilities for application of different heat exchangers in exhaust gases system of gas radiant heaters. The authors propose to classify exhaust gas heat recovery systems in dependence on intermediary medium: water/air, gas heaters type: ceramic/tube and number (single/group) and their mounting location.
