The burner can be automatically controlled in many ways. In this control, the burner starts automatically, ignites the oil, and regulates the firing rate to follow the load while it is in operation. It is necessary that the presence of an operator to start or shut down the burner but is equipped with controls that automatically regulate the rate of firing while the burner is in operation. The flow of oil, primary air, and secondary air can be adjusted separately, or arrangements can be made to adjust them simultaneously. It requires the presence of an operator to start and shut down the burner and to regulate the firing rate while it is in operation. There are three types of control systems that can be used with the horizontal rotary oil burner: This type of burner enters the boiler or furnace on a horizontal plane, and prepares oil for combustion by centrifugal force.ДЇuel is atomized by a horizontal rotary burner by a combined action of the atomizing cup and the primary air stream.

We discuss three popular burners used in industries.

Oil burners for industrial use are usually classified according to the method used for atomizing the oil. A poor burner does not accomplish this task well at all. The good burner mixes well and liberates a maximum amount of heat from the fuel. The performance of the burner is achieved by proper air-fuel mixing. This act requires the combustion of the fuel, but the combustion takes place outside the burner, that is at the tip. The purpose of the burner is to mix the fuel with enough air to cause heat release from the fuel. This article focuses mainly on popular industrial oil burners. Those used in conjunction with domestic heating systems and those used in industrial heating systems.

Paraffins and Alkanes - Combustion Properties - Properties like heat values, air/fuel ratios, flame speed, flame temperatures, ignition temperatures, flash points and flammability limits.Oil burners basically may be divided into two groups.

Fuels Flue Gases - Average Dew Points - Flue gas dew point temperatures for some fuels.

Fuel Oil Pumps - Suction Capacities - Single stage and double stage fuel oil pumps and their suction capacities.

Fuel Oil Burners - Pot types, gun types and rotary types fuel burners.

Flue Gases - Dew Point Temperatures - Flue gas dew point temperatures and condensation of water vapor.

Combustion Processes and Combustion Efficiency - Typical furnace combustion efficiencies in fireplaces, space heaters, boilers and more.

Combustion Efficiency and Excess Air - Optimizing boilers efficiency is important to minimize fuel consumption and unwanted excess to the environment.

Boiler - Efficiency - Combustion gross and net calorific value.

Combustion - Boiler house topics, fuels like oil, gas, coal, wood - chimneys, safety valves, tanks - combustion efficiency.

Typical values are between 330 - 500 oF ( 160 - 260 oC). Net stack temperatures above 700 oF ( 370 oC) are in general to high. The 'net stack temperature' is the difference between the flue gas inside the chimney and the room temperature outside the burner.

excessive air leaks in boiler or furnace.

poor fuel supply, malfunctioning fuel pump.

insufficient draft, incorrectly adjusted draft regulator, improper fan delivery.

The amount of smoke can be measured with a smoke tester where smoke particles set on a filter paper are interpreted according a Bacharach scale. Smoke in flue gas indicates poor burner performance. High carbon dioxide content may be caused by When the CO 2 content of the flue gas is too high it is common with excess smoke in the flue gas. Low carbon dioxide content may be caused by When the CO 2 content of the flue gas is low (less than 8 percent) heat is lost up the chimney and the operation is inefficient. To secure safe and efficient operation of gas or fuel oil burners it is common to test the burners for
