Attending to the selectivity a low CO2 flow rate favored the production of fuels such as methane (5.2 10–3 mmol h–1) and methanol (3.6 10–4 mmol h–1). These results indicate that the supercritical synthesis of the Pt/CNT electrocatalyst improves the results reported in the literature up to now.

The burner used for the study was an IFRF 1.5 x 106 Btu/hr wall- mounted unit. This burner is a versatile experimental swirl block burner patterned after that developed by Beer (Reference 5). During baseline tests on the parent coals a Babcock and Wilcox-type coal spreader was used to

High-temperature materials for power generation in gas

 · Electron beam-physical vapor deposition. Electron beam-physical vapor deposition (EB-PVD) utilizes an electron gun to vaporize the coating material the so-called ingot in the form of a rod. To allow the passage of electrons to the evaporation material the deposition chamber must be evacuated to a pressure of at least 10 − 2 Pa. A magnetic field is employed to direct the electron beam from its

A review of some operation and maintenance issues of CFBC

 · Refractory is a major maintenance item in a circulating fluidized bed (CFB) boiler whose greater part of interior is lined with refractory . The operating characteristics of CFBs require its refractory materials to withstand abrasion from circulating particles as large as 6 mm and thermal cycling along with temperatures in the range of 700

Energies Free Full-Text A Critical Review of Mineral

Refractory degradation occurs in several ways—penetration of slag into refractory changes the physical and chemical properties of refractory layer resulting in the formation of cracks direct abrasion by ash and slag chemical dissolution of refractory by slag spalling of refractory due to thermal fluctuations and corrosion of refractory due to process gas 21 22 . Not much has been reported in the open literature on refractory
