Proper Combustion Load Testing Keeps Boilers Running

Boiler Questions and Answers regarding Your Boiler

If a loss of heat for 1/2 hour to 1 hours would not cause any problems then running only one boiler is the preferred method. In your case I would run only one boiler at a time. Have one boiler in standby fired every few hours just to keep warm and the last boiler completely off and isolated. Now, everyone has their own opinion.

What is a flame safeguard system

A flame safeguard system also starts the burner in the proper sequence. For example it will purge the combustion chamber of gas, light the pilot and then open the main gas valve. The flame safeguard system will also continually monitor burner operation when the boiler is on-line.

How to Destroy a Boiler -- Part 1

Boilers are blown up every year as a result of poor atomization of oil which results in incomplete combustion and can lead to unburned oil puddling on the floor of the furnace. To prevent this, the oil tips must be clean, the oil temperature must be correct, the oil viscosity must be in spec, and the atomizing steam (or air) pressure and fuel

Boiler Efficiency - an overview | ScienceDirect Topics

The most common test used for boilers is the flue gas analysis using an Orsat apparatus to determine the percentage by volume the amount of CO 2, CO, O 2, and N 2 in the combustion gas leaving the stack. Based on the flue gas composition and temperature, some adjustments can be made to tune-up the boiler and to determine the best air-to-fuel

High Pressure Boiler: What is it? Types & Characteristics

The division of megapascal pressure (MPa) determines whether a boiler is low and high pressure. Boilers that produce pressure above 80 MPa are considered to be high pressure. Low pressure boilers have a MPa below 80 MPa. Water circulation can be forced or natural. If the water is pumped, it is forced.
