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. […]
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. […]
