Engineered Systems - February 2008 - (Page 34) Chipping Away At Emissions tapered hopper and passes through a rotary air lock to a either dumpster or drag chain conveyor for removal, or to a fan-driven re-injection line back into the combustion chamber. The secondary collector contains a larger number of smaller cast iron and steel tube configurations, and approximately 95% of the remaining finer particulate matter is removed here. Fauteux said he knows the emission controls on the new boilers are working because the hospitals are no longer identified by the big black clouds hovering over the buildings. “It used to be you didn’t have to get directions to get to the hospitals — all you had to do was watch for the smoke coming out. Now you have to watch for the signs, because you’ll never get there otherwise.” SAME SYSTEM USED EVERYWHERE The same hybrid boiler system will be installed at all the other Quebec hospitals in which Fauteux is involved for two reasons. First, the government is comfortable with this particular technology, and second, keeping the same The system is designed to provide a minimal reserve of fuel through the use of a metering bin that is fitted with a level indicating device. As the load on the energy system is increased, the level of fuel is lowered in the bin. A metering screw below the bin transports the fuel to a stoker screw which then feeds the fuel into the boiler. (with envy) At Berner International and Berner Energy Recovery, we’re proud to be recognized for our contributions to improving indoor air quality and the green movement. Over the past several years, we’ve been developing technology and manufacturing products that help everyone breathe a little easier and save energy. We were the first to bring air curtain technology to the United States, and we are an innovator in fresh air energy recovery systems for schools, hospitals and others. So, it’s understandable what the reaction from others would be. First in environments above and beyond. just ask.
