Apr 01 2018 · MEANS AND METHOD FOR PRODUCING A VACUUM. DOEpatents. Otavka M.A. . A new method is given for starting the operation of evapor-ion vacuum pumps. Ordinarily this type of pump is started by inducing an electric field with the vacuum chamber however by placing such an electric field in the chamber at the outset a glow discharge may be initiated which is harmful Because the major component of the brick was MgO the ternary system CaOMgOSiO2 can be used to view the corrosion processes as a first approximation (Figure 15). In the case of the 90 MgO class refractory the brick contained 95.5 MgO 2.7 CaO and 1.4 SiO2.

Kinetic study on CO2 gasification of brown coal and
Jun 01 2016 · When Rhenish brown coal and wheat straw chars were gasified at 800 °C the reaction order of WS-E was much higher than that of HKN-E (0.62 compared to 0.38). However at 1000 °C the reaction order was 0.66 for WS-E compared to 0.72 for HKN-E showing that the dependence on CO 2 concentration was similar during the gasification process For the purpose to extend the service life of MgO-C bricks used as linings of vanadium-extraction converters MgO-Fe-C bricks with different carbon content were designed and the properties of this
