Pressure can strongly affect the thermal conversion characteristics of coal. This work used a pressurized horizontal furnace to study the pyrolysis (Ar) and O 2 /H 2 O (10 vol%/25 vol%) thermal conversion characteristics of demineralized coal under different pressure (0.1–1.5 MPa) and at 1000 °C. The changes of carbon conversion, pore …

Airflow configuration — upflow, downflow, and horizontal flow — is just one factor you might need to consider. Upflow furnaces are great for homes with the furnace installed in the basement, while downflow furnaces work well when the furnace is in an attic. Horizontal-flow furnaces are ideal for homes with limited space.
There are three main methods of firing pulverized coal in a furnace. Based on their orientation in the furnace these are classified into horizontal (opposed jet or front firing), down-shot, and corner firing. The horizontal and down-shot firing burners are described in Chapter 9. The present chapter describes operating principles

Air furnaces are of different types including stove, pipe less furnace, forced air or direct fired heaters. Different types of air furnaces may use coke, wood coal or kerosene as their fuel. This article provides an introduction to forced air furnaces and also provides guidance for selecting a modern furnace based on the area to be heated and the typical heat loss …
Over-fire air is introduced to achieve deep staging conditions for combustion optimization in a 0.7MW arch-fired furnace. The momentum flux ratio (M) of vertical to horizontal component is determined by variations of air distribution and the inclination angle of the F-layer secondary air. Two coals with relatively large characteristic differences are used in …
