The Importance of Sensing Lines to Performance of Boiler Room Instrumentation
-By David Eoff Sensing lines are everywhere in the modern plant, whether it be a boiler plant, refinery, chemical plant, or water treatment plant. Often the instrumentation problems that stump operators, contractors, and sometimes full-time service technicians are related to how sensing lines are installed and maintained. We’re going to examine some of the most common instruments that […]

Tips and Tricks for Proper Feedwater Control
1. Feedwater Valve Selection: Although the feedwater valve must be designed so that it will flow the required water for full boiler steaming capacity, the flow rate from blowdown and the relief valves opening must also be factored into the sizing of the feedwater flow control valve. It is important not to oversize the valve too much to accommodate blowdown and pressure relief. A […]
Tips and Tricks for Installation and Operation of Draft Control
-Dan Wallace, PE 1. Make sure tubing is pitched downward to avoid condensation in the impulse lines. Liquid in the impulse lines can cause incorrect draft measurements and have adverse effects on fired equipment operation. 2. If the draft pressure sensor is located below the sensing point, ensure there is an adequate drip leg to collect condensation. 3. […]
NYC Local Law 87 Compliant Draft Control Strategy
Joe Wallace The induced draft (ID) fans at many NYC Department of Education schools are grossly over sized, causing problems including noncompliance with local regulations. These old boilers are not equipped with forced draft fans and rely on these induced draft fans, installed on the flue of the boiler, to create draft. Typically, these ID fans run at full […]
Combustion Tuning a Parallel Positioning System
-Dan Wallace, PE Follow these best practices to tune a Natural Gas burner. 1. Check the burner nameplate for the required gas pressure at the manifold at high fire. 2. Check the burner nameplate for the required supply pressure. 3. Light the burner off, and adjust the main gas pressure regulator until the desired supply pressure is obtained. […]
Nuclear Power: Clean and Sustainable
When we think “clean energy,” we often imagine fields of solar panels or wind turbines, but how often do we think of nuclear energy? Unfortunately, although nuclear is the second largest source of low-carbon electricity in the world behind hydropower, its often left out of the “clean energy” discussion. 1. Nuclear energy protects air quality Nuclear is a […]
