[Steam-engine] Small hand hole plates

[Francis Orr]

Spencer, traction engines aren't to bad for mud but the term"mud drum"
really came into its own with the steamboats. They pulled their feedwater
direct from the river and "mud" there certainly was! Another thing can
happen that is not quite so visible as mud but as you boil the water, the
impurities in the water stay in the boiler and increase. They tend to settle
down around the mud ring. Impurities are not good so most boiler operator
instuctions include a statement about a "bottom blow" to get rid of these
impurities. Some impurities are light and will float on the top of the
water. Therefore, marine and high performance stationary boilers include
piping provisions for a "top blow." And--don't use rainwater for boiler
feed. It is full of oxygen which is the major killer of hobby boilers.
