Boiler Efficiency - an overview | ScienceDirect Topics

Typical boiler efficiencies range from about 90% for the best solid biomass fuel boilers to close to 95% for oil- and natural gas-fired boilers Table 3.2. The main reason for the poorer performance of biofuels is the high moisture content of the fuel which increases flue gas losses.

Boiler Operation Maintenance & Safety Study Guide Boiler ...

Natural draft furnaces naturally operate below atmospheric pressure.An induced draft fan draws the gases through the furnace and the combustion air into the furnace. An induced draft fan is located between the boiler and the stack and makes high stacks unnecessary. Control is accomplished by regulating the fan speed or damper operation.

Plant Engineering | Maintaining boiler safety

All properly designed installations both gas/oil and solid fuel units should be installed with redundant and dissimilar low-water trips conductive and float-actuated types. Unfortunately an alarming number of boilers equipped with low-water trips are destroyed each year. There are several common reasons for low-water trip failures.

Boiler Combustion | CleanBoiler.org

Enlarging the flame results in lower flame temperatures and lower thermal NOx formation which in turn results in lower overall NOx emissions. The technology can be applied to most boiler types and sizes. It is most effective when firing natural gas and distillate fuel oil and has little affect on boilers firing heavy oil.

How to Destroy a Boiler -- Part 1

High conductivity or contamination of the boiler feedwater can create other problems such as drum level instability and foaming. This can result in high or low-water alarms and an increase in the carryover of moisture droplets into the steam header since the moisture separator of the drum cannot handle the resultant carryover.

Boiler Fan Fault Problems And Cures - Electrical

The fan on your boiler from a safety perspective is one of the most important components. It doesnt act like a fan on other machinery such as cars (i.e. cooling the cars engine down). Instead the fan on a boiler helps to drive harmful gases out of the flue. Without the fan

Induction Heating: What It Is How it Works

With conductive materials about 85% of the heating effect occurs on the surface or "skin" of the part; the heating intensity diminishes as the distance from the surface increases.So small or thin parts generally heat more quickly than large thick parts especially if the

CAUSES OF DAMAGES TO THE BOILER (PART-2)

Jun 01 2017 · Overheating of boiler heating surfaces by oil occurs because the oil forms a thin film on the surface. The film acts as an insulator that retards the heat transfer process.

Operation of Boiler and Conductivity in Drum Water and ...

Dec 23 2009 · Water chemistry sensors for both feed water and boiler need monitoring as any impurities in this gets concentrated and gets carried over in the steam. Conductivity controls for water blowdown in the drum type boiler are a method to remove such concentrate. Conductivity is just one of many factors to monitor. Changes in conductivity readings in various area gives a good clue to operators to ...
