Fire-tube boilers may be designed for vertical, inclined, or horizontal positions. One of the most generally used types is the horizontal-return-tube (HRT) boiler. In the HRT boiler, part of the heat from the combustion gases is transferred directly to the lower portion of the shell.

An oil burner is defined by the National Oil Fuel Institute as a mechanical device for preparing fuel oil to combine with air under controlled conditions for combustion. Two methods(atomization and vaporization) are used for the preparation of fuel oil for the combustion process. Air for combustion is supplied by natural or mechanical draft. Ignition is generally accomplished by an electric spark, gas pilot flame, or oil pilot flame. Burners of different types operate with luminous or nonluminous flame. Operation may be continuous, intermittent, modulating, or high-low flame.  4, record 4, English, - oil%20burner

Gas-fired water heaters have a gas burner located below the tank, a thermostatic switch, a gas valve and a pilot light. The thermostat will open the gas valve when it senses the water temperature at the bottom of the tank has dropped below the present limit. Gas flows to the burner and is ignited by the pilot light, heating the tank from below. In addition, the hot exhaust gases are vented through a hollow core in the center of the tank to help heat the water. The exhaust is then passed into the draft hood and to the vent connector where it is discharged to a chimney flue.  3, record 8, English, - gas%20water%20heater

There are two sub-types : pure suspension and cyclonic. Pure suspension units are true "burners" in that a stable open flame(similar to a gas or oil burner flame) is created by air jets that are usually mounted in the wall of the combustor or boiler. Cyclonic suspension units have a refractory cylindrical combustion chamber into which the fuel particles and air are introduced tangentially. The long cyclonic gas circulation keeps the fuel circulating in the chamber, resulting in complete combustion of the fuel, but all ash normally exits with the hot exhaust gases. Fuel is fed to both types of these burners by pneumatic feeders with the fuel air stream forming the primary air supply.  2, record 22, English, - suspension%20burner

As gas comes out of the ports or holes in the burner, it mixes with more air and the mixture is ignited.(The burner is scientifically designed to be adjusted for the correct amount of gas and air for the particular burner.)  3, record 41, English, - mixer%20tube

The Pactrol CSA provides automatic ignition control and flame supervision for gas burners ... The control provides a short pre-purge period followed by an ignition period, and there is a choice of alternative timings. Flame supervision is by flame rectification, with the option of ultra-violet sensing with the addition of a special UV head. The control will shut-down and provide volatile lock-out following flame-failure or an unsuccessful ignition attempt, and may be reset by interrupting the electrical supply.  3, record 42, English, - flame%20rectification

An inspirator mixer, does not require a blower but does require high pressure gas,(can be dangerous) and is not very economical or efficient. The tip or nozzle is usually always a flame retention type tip. The reason this burner requires high pressure gas is that the gas needs to be moving at a high rate of speed in order to induce enough air for proper combustion. It is usually used for propane and in a situation where no electricity is available. If you have high pressure gas it is recommended that you use a regulator and switch to an aspirator mixer type system.  3, record 43, English, - inspirator%20mixer

A mechanical-draft burner which uses the energy of high-pressure gas(10 to 50 psi) to completely premix the air and gas. Gas is permitted to escape through a row of small orifices on the edge of propeller-like blades mounted on a free-spinning shaft. Reaction of the escaping gas rotates the blades, which are mechanically coupled to a fan that draws in the primary air. The speed of the fan varies with the gas pressure, thereby automatically adjusting the air volume to maintain optimum combustion.  1, record 47, English, - Fanmix%20burner

A power burner in which a fan, or blower, blows air at high velocity past turbulators. The gas, at regulated pressure, is released into the turbulent airstream-typically from a ring at the mouth of the burner(in which case it is also called a ring burner). The gas escapes through orifices around the periphery of the ring. Gas and air are adjusted simultaneously to maintain the proper air-fuel ratio as the firing rate changes. In high-pressure gun burners, the gas is ejected at pressures up to 15 psi from spuds located in the center of the turbulent airstream instead of at the outside.  1, record 50, English, - gun%20type%20burner
