Control system for modular boiler plants
AERCO Control System (ACS) is a flexible controller designed to maximize energy savings in modular boiler plants.
The AERCO Control System (ACS) is a flexible controller designed to maximize energy savings in modular boiler plants. The ACS can stage and coordinate the operations of up to 32 boilers and is uniquely designed to maximize the operating efficiency of condensing equipment. Eight of these 32 boilers can be designated for domestic heating priority. Another eight boilers may be designated as swing boilers serving domestic hot water and building space heating as demand requires. With individual unit turndown as high as 20:1, a five-boiler plant delivers 100:1 system turndown when staged to operate sequentially. Able to regulate overall plant output with precise accuracy, a boiler plant with ±2 F header temperature variation is assured under normal load conditions. The ACS offers sequential or parallel operation flexibility, 100% control of auxiliary equipment, and user programmable modes of operation that can be changed in the field. It automatically rotates the lead unit to help equalize boiler runtime.
Annual Salary Survey
After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.
The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
