Fuel oil firing

Here q, is the latent heat of vaporization. The heat transfer number, V/ represents the ratio of the vaporization potential of the ambient environment to the vaporization energy requirement of the liquid fuel. Integrating Equation (6.32) yields 

Equation (6.34) is the so-called d law which shows that the square of the droplet diameter decreases linearly with time. The equation also reveals that the residence time for complete consumption of a droplet may be expressed as 

This demonstrates a quadratic dependence of burnout on the diameter of the initial liquid droplet. For burning droplets, the droplet flame front acts as a nearby source of heat for droplet vaporization, otherwise the mechanism is the same as pure vaporization. For a singlecomponent, uniform droplet burning under quasi-steady gas-phase conditions

To date, the test program has consisted of two periods of No. 6 fuel oil firing, two periods of SRC-II firing, and two combustion runs on No. 2 oil. Each test period was preceded by a few brief tests to shake down the boiler and determine settings for the atomizing air flow, fuel preheat temperature, and fuel/air proportioning controller. To date, eight runs have been made with No. 6 oil five at about 23% excess air and three at about 11 excess air. Two runs have been completed on No. 2 oil one at 11% excess air and one at 20% excess air. Five SRC-II fuels have been tested a...

A soot blower mechanically cleans soot build-up on conveaion section tubes in fuel-oil-fired heaters. A soot blower essentially consists of a lance (i.e., pipe) with nozzles spedfically located for the tube section to be deaned and a connection for the blowing medium, which is steam or air. There are two types of blowers fixed and retractable. 

SOx Abatement. Fuel-oil fired heaters and the regenerators of FCC units are major sources of refinery SOx and NOx emissions. The most obvious way to reduce SOx emissions from a heater is to use low-sulfur fuels. Unfortunately, although that solution requires no investment, it is probably...
