(3) modify oil-fired boilers to fire coal slurry; 4. (4) modify boilers to fire deeply cleaned finely pulverized coal; or. 5. (5) fire coal-derived liquids. Of these alternatives the use of the coal-water slurry (CWS) promised a combination of advantages: near-term readiness low-fuel costs compared to oil moderate conversion costs and low ...

With the addition of a condensing economizer boiler efficiency improvements up to 10% are possible. Condensing economizers can also capture flue gas particulates. In this work the potential use of condensing economizers for both efficiency improvement and control of particulate emissions from small coal water slurry-fired boilers was evaluated. Analysis was done to predict heat transfer and

The coal-water slurry (CWS) is a potential new form of fuel for application in power boilers and industrial furnaces. The single suspended coal-water slurry droplets have been burned in hot gas streams to reveal their basic nature of evaporation and heating processes. Temperature measurement and microscopic observation are performed.

A comprehensive three-dimensional numerical model is developed for simulation of the industrial opposed multiburner (OMB) coalwater slurry (CWS) entrained flow gasifier. The CWS gasification process is divided into several submodels including water evaporation coal pyrolysis and homogeneous and heterogeneous char reactions. The effectiveness factor method is used to extrapolate the ...

The primary objective is to develop the design base for prototype commercial advanced fine coal cleaning facilities capable of producing ultra-clean coals suitable for conversion to coal-water slurry fuel. The fine coal cleaning technologies are advanced column flotation and selective agglomeration. A secondary objective is to develop the design base for near-term commercial integration of advanced fine coal cleaning technologies in new or existing coal

Abstract. Coal-water slurries are promising fuels for thermal power engineering. One of the main problems with their combustion is formation of fairly large (with characteristic sizes of more than 1 mm) droplets during spraying with nozzles. It results in their late ignition in
Read MoreP. GoldsWorthy ... E. On in The Coal Handbook: Towards Cleaner Production: Coal Utilisation 2013. Boiler efficiency and carbon burnout. Boiler efficiency is a measure of how effectively chemical energy in fuel is converted into heat energy in steam going to the turbines. The largest boiler efficiency loss is sensible heat lost as hot flue gases (and ash) exit the boiler.
