SOLUTIONS FOR COVID-19

coronavirus and other germs and viruses...Reimers also has easy to use portable sterilizers too!

Testing done at DHS' advanced bio containment lab in Maryland, said the virus' half life plunges "drastically" with exposure to higher temperatures and even minimal exposure to humidity.

How Circulating Fluidized Bed Boilers Wor

Circulating Fluidized Bed (CFB) combustion boilers gives the flexibility for combustion of a wide range of coals and alternative fuel sources. All this without compromising efficiency and with reduced emissions. This article gives a brief description of the working of a CFB boiler. At the bottom of the boiler furnace there is a bed of inert material.

combustion of coal. In coal utilization: Fluidized bed In fluidized-bed combustion, a bed of crushed solid particles (usually six millimetres or less) is made to behave like a fluid by an airstream passing from the bottom of the bed at sufficient velocity to suspend the material in it. The bed material—usually….

Fluidized Bed Combustors for Biomass Boilers - AS

Fluidized-bed boilers are the most common type of boiler recommended for biomass fuel, which is burned within a hot bed of inert particles, typically sand. The fuel-particle mix is suspended by an upward flow of combustion air within the bed. As velocities increase the gas/solid mix exhibits fluid-like …
