Use of Gas Lasers in Metal Processing

USE OF GAS LASERS IN METAL                                                                                                        PROCESSING INTRODUCTION Gas lasers are lasers that can produce consistent beams of light with short wavelengths when an electric current is passed through a gas (or plasma) (Bloom, 1968).Plasma is an ionised gas with relatively no charge (SPI Lasers, 2018), it is the fourth state of matter. The first…

Investigation of the Techno-economic Feasibility of Recovering Waste Heat of Diesel Generator Exhaust

INVESTIGATION OF THE TECHNO-ECONOMIC FEASIBILITY OF RECOVERING WASTE HEAT OF DIESEL GENERATOR EXHAUST FOR HEATING MINE INTAKE AIR ABSTRACT In cold climates, extremely harsh winters require heating of underground mine intake air. As a result, fresh intake air, as cold as -40°C, is commonly heated up to around +3 °C, leading to high energy costs…
