Boiler fuel heavy liquid

It is anticipated that coal derived liquids boiling above about 350 F will be disposed of to the utility market. Table V summarizes the potential utility markets for various types of coal derived fuels which include solvent refined coal, heavy boiler fuels, distillate boiler fuels, turbine fuels and methanol. Speculative locations for these markets are indicated on Figure 2. 

The results of the experiments. The material balance of the light cracking of fuel oil with recycling of the heavy reflux (when the residue contains liquid boiler fuel of given viscosity) was calculated on the basis of works data for single cracking of fuel oil and laboratory data for multiple tandem cracking of the recycle material. 

NOTE Where smoke suppression is required (e.g., in a boiler fired on poor-quality heavy fuel oil) and a typical liquid combustion improver product is employed, to achieve a 35% reduction in unbumed particles may require the addition of 2/3 pint of additive per 2,500 gallons of fuel (approximately 0.33 liters per 10m3). Doubling the smoke particle reduction to 65%, however, may require triple the feed rate of the additive. 

Fast pyrolysis liquid may be envisioned to replace either light or heavy fuel oil. Typically these oils are used as boiler and engine power plant fuels. 

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... 

In order to limit thermal stresses and to reduce corrosion of the steel vessel, the reflector temperature was regulated near 350°F. About 50 kw of heat conducted from the fuel core to the reflector liquid was removed by circulating the heavy water with a 30-gpm canned-rotor pump through a reflector cooler which acted as a boiler feedwater preheater. A jet was located in this high-pressure circulating loop, the suction of which drew a continuous stream of gas from the vapor space above the reflector to a catalytic recombiner so that the concentration of deuterium and oxygen gases in this vapor space could be kept below explosive limits.
