Engineered Systems - February 2008 - (Page 36) Chipping Away At Emissions A metering screw located ee g immediately below the metering bin is used to transport the fuel, at a , ty measured rate, to a rotary air lock device. The air lock t f device acts as a draft barrier, allowing fuel to pass from the metering screw to e ig the stoker screw while limiting the intrusion of air t through the fuel system. The stoker then brings the fuel into the boiler. system results in fewer spare parts being needed by the hospitals. “The government wanted to have one central location in the north FREE INFO: 26 that doesn’t have to supply parts for 20 different kinds of boilers,” said Fauteux. “This is a good move for their budget, because they can supply all the hospitals through one warehouse, because all the motors ESM05074Lat.indd 1 4/13/07 8:49:19 AM and drives are the same from place to place. There isn’t a heavy budget for spare parts in each hospital.” Using the same boiler system at the different locations will also be easier for hospital personnel, who are having to adjust to using a The experts in stainless computer to control the equipment. “They had to get used to this new steel clean air systems technology. It won’t bite. If necessary, all they have to do is shut down the boiler, and then they restart it. It’s not that complicated. They for waste water really appreciate that now they can shut down the boiler from their treatment facilities, home or office, or make corrections without going over there.” Neither hospital has been through a complete season, so a full plus: energy assessment hasn’t been made. However, Fauteux believes each • Custom fabrication facility is saving 40% to 45% in their energy costs, compared to what • Rush deliveries they were paying previously. And most importantly, the boilers passed the stringent emissions tests conducted by the government. A-J Manufacturing offers a complete line of custom “They haven’t decided which hospital we will work on next,” said and standard stainless steel air distribution products, all Fauteux, “but now that we have the boiler system down, each job will designed and manufactured to offer durable, dependable move a little faster.” ES and low maintenance performance necessary for waste water treatment facilities.
