Coal is pulverized in large mills, and the powder is mixed with air and transported by air pressure, through pipes, to the burners. The coal transport from the yard to the mills requires automated transporter belts, hoppers, and sometimes manually operated bulldozers.

Warm air seeks gaps in the insulation, and when it hits colder surfaces as it flows out of or into the house, water condenses—which then feeds mold. These spots often occur on outside walls near floors or windows, at corners and around outlets and lights.

Although small air gaps do not affect heat loss via convection, their thermal resistive properties should be analyzed to determine the contribution to system heat loss through conduction. To illustrate, suppose the pipe shown in figure 1 consists of 1" fiberglass insulation, and the air gap between the pipe wall and insulation is 0.05".
