Burners liquid fuel

Liquid fuels. Industrial burners for liquid fuels usually atomize the fuels in hot air so that droplets will evaporate during combustion. For more volatile fuels such as kerosine, vaporizing burners of various types are employed, usually for domestic purposes. 

Fuels gas of 1000 Btu/SCF at 5-10 psig, or up to 25 psig for some types of burners liquid at 6 million Btu/barrel. 

The burners are positioned at base or sides of radiant section. Gaseous and liquid fuels are used. The combustion air may be preheated in tubes in the convection section. 

COSILAB Combustion Simulation Software is a set of commercial software tools for simulating a variety of laminar flames including unstrained, premixed freely propagating flames, unstrained, premixed burner-stabilized flames, strained premixed flames, strained diffusion flames, strained partially premixed flames cylindrical and spherical symmetrical flames. The code can simulate transient spherically expanding and converging flames, droplets and streams of droplets in flames, sprays, tubular flames, combustion and/or evaporation of single spherical drops of liquid fuel, reactions in plug flow and perfectly stirred reactors, and problems of reactive boundary layers, such as open or enclosed jet flames, or flames in a wall boundary layer. The codes were developed from RUN-1DL, described below, and are now maintained and distributed by SoftPredict.

Burners may be located in the floor or on the ends of the heaters. Liquid fuels are atomized with steam or air or mechanically. A particularly effective heater design is equipped with radiant panel (surface combustion) burners, illustrated in Figure 17.16(a), (b). The incandescent walls are located 2-3 ft from the tubes. The furnace side of the panel may reach 2200°F whereas the outer side remains at 120°F because of continual cooling by the air-gas mixture. Radiant panel burners require only 2-5% excess... 

In a vapor-absorption refrigeration system, there are no moving parts. The added energy comes from a gas or liquid fuel burner or from an electrical heater, as heat. rather than from a compressor, as work. See Fig. 2. The refrigerant used in this example is ammonia gas. which is liberated from a water solution and transported from one region to another by the aid of hydrogen, The total pressure throughout the system is constant and therefore no valves axe needed. 

The burner of type Oilon Lenox GRT-5L is a mixing burner for oil and gas combustion in boilers. The burner was equipped with the dual fuel lance, which enables the use of two different liquid fuels either separately or simultaneously. Heavy fuel oil (PORL 180) was used as support and start up fuel. A KM-nozzle type...
