Wagon-boiler and boiler furnace
The model is built as pair-horse, very robust and with very big capacity of the
boiler furnace. The boiler is made from iron (certification including). Heating
tubing diameter is 14mm and tubing are clean so far. Be enough insufflate for them
by compressed air after working day. Hole into boiler furnace is biggish so that
steam attendance needn´t fragmentate coal. An anthracite is best for steam engine,
but you can use less quality coal at the expense of higher volume of the smoke.
Coal quality is very important for amount of unburned particle which settled in the
smoke-box. Frequently check-on smoke-box is recommended. Too large plurality of
the unburned particle confines boiler draught and it causes marked fall of steam
pressure.
The steam engine has got two-piece fire grate which you can easily take out by
slot above engine floor. But ash falls on wheels and crank gear.
Steam and oil distribution, steam engine operation
Loads of steam admision into two cylinders interlocks steam regulator. Steam regulator
is placed in the middle part above boiler furnace. Cylinders has got water drain
valves which have control over lever in left front part. Water drain valves open
off while a drive-away of steam engine in order to ablation condensed steam from
cylinders. There is a steam gauge for check on pressure. Steam engine gets rolling
from 5 PSI pressure and it is able to ride-out some few meters with 3 PSI. Safety
valves are set at 10 PSI - we alerady know, when safety valves burst up on our
steam engine, because they have very specific sound.
Forced feed lubricator with ratchet-wheel ensures lubrication of steam cylinders.
It is placed on the right side. Oil tank is not very bulky for two cylinders and
capacity of an oil is relatively small - endurance is about 1500m.
Cranked adjusting if you like control driving direction is ensured by reverser level.
This lever is placed at front right side of engine cab. The reverser has got five
positions - two positions for forward running, two positions for reverse running and
neutral position.
The steam engine has got mechanical brake. Brake has control over crank-handle
at left side of engine cab. There is not much place for crank movement, but if
engine driver looks "sufficiently" forwardly, engine steam safely halts with full
laden train. The steam engine has got whistle, too. Whistle has control over level
at top part of boiler furnace.
Controls are all-metall and you can service them without gloves. But be careful
while open water drain valves.
Water
Water supply is solved through hose system from a reservoir in service car. We must
fill a water to boiler by hand pump before heating-up. The axle pump is in service
during the riding. We can throw over a water circulation back to reservoir by the
bypass valve. The steam engine has got a steam pump and injector, which we use during
longer staying in the station. We can blow off water from boiler by the blow valve
at right bottom part of steam engine.
