gas boiler response measures

Utility Emergency Response Procedure - Northeast Gas

When boilers or furnaces experience an overheated condition, catastrophic damage to the heating unit, safety controls and components is likely. This emergency condition should be treated with a similar response to an inside gas leak with open air gas readings 1% or greater. In these cases, service technicians are expected to evacuate all occupants (including

4 key measurements for optimal boiler control | PI Process

Jan 01, 2016 · Using this technique, the true nature of the flow profile can be determined, and a reliable air flow measurement (typically, accurate to about 2 percent with good repeatability) can be obtained where it is needed on the boiler. Oxygen measurement. The flue gas oxygen measurement at the back end of a boiler is arguably the most critical parameter used by the combustion control strategy.

Precautions when operating the boiler and exhaust gas

A gas/oil boiler has no inventory or bed of fuel. When you trip the burner, for all practical purposes, the heat input immediately stops. With solid fuel units, however, a fairly large mass of bark, coal, etc., is still on the grate and even though starved of air by the loss of the forced draft fan, these units have more "thermal inertia" and

2-1 Recausticizing - Principles and Practice

Hot boiler feedwater in conjunction with dissolved residual oxygen this means corrosion for the plant units from the pipe to the turbine on the one hand and high maintenance and repair costs on the other hand. To prevent this, oxygen-consuming chemicals are added to the boiler feedwater. The effectiveness of these chemicals must be monitored.

The Importance of Boiler Water and Steam Chemistry

Dissolved gases such as carbon dioxide and oxygen cause boiler corrosion and must be removed by deaeration and other methods of treatment. Because dissolved minerals cause scale, corrosion, and turbine blade deposits, boiler feedwater must be treated with lime or soda ash to precipitate these min- erals from the water.
