The snow melting pits are in several prefectures and work well,
why not copy them for Boston?
A snow melting pit would take up little room as the pit itself is
narrow very deep and long to allow four or five trucks wide to
dump at one time.
For that matter a small wheel loader with a plow blade could be used
to push dumped snow into the receiving pit to reduce any chance of
the haulage truck causing any damage to the building and this would
allow large dump trailers to haul snow to a snow melting pit site with
speed as the snow would just be dumped and pushed into the melting
pit later.
A small anthracite coal stoker boiler consumes a small amount of coal
per hour and can heat huge amounts of water to 180 degrees quickly.
A melt pit that is 20 feet wide 80 feet long and 40 feet deep would hold
80 by 40 by 20=64,000 thousand cubic feet of water times 6.84251
which is the number of gallons of water that occupies a cubic foot
equals 437,921 gallons of heated water in total volume(rounded higher).
So if the pit was filled to seventy percent of its volume with hot water it
would have 306,545 gallons (rounded higher) of hot water for melting it would
continue melt the snow and ice into liquid that would eventually reach the scupper
drains and flow to Deere Island eventually from the storage basins.
Saying that The melt water is heated to 180 degrees on a continuous basis and becomes
the heat source to aid in melting more snow and ice and the water temperature could be
increased to two hundred degrees to increase the heat and melting power available to
reduce the snow to liquid and the melt pit would also be evaporating the melt water as a
steam vapor at the same time.
A battery of coal stokers would provide all the hot water needed to melt the snow at all hours.
The coal bins of the stokers would have to be filled and the boilers would have a closed loop
water system that could be fed from a pressure tank that receives city water.
The 300,000 plus gallons of heated water that would be in the pit is huge energy source that could be counted
on to do the work quickly as it is done on Hokkaido Island. The snow would melt quickly and would add to the thermal mass available to melt the snow that is being dumped as soon as the other truck pulls out. I am sorry I do not have a
link to the Youtube video that I viewed showing how quickly they were dumping and melting the snow.
Piping the 8 plus boilers in series would provide a huge amount of hot water.
The use of a Victaulic piping system would be quick and easy to repair if a leak was found as the pit could be pumped out quickly and the pipe gasket repaired quickly using a steel floating work platform that would be lowered into the pit.
Compressed air would be used to find the leak quickly and the plan of repair could be done quickly.
The one inch Victaulic pipe could be used in long pipe runs with a single eighty foot joint connecting to the end wall pipe joints providing a 200 foot loop of pipe that would have 160-180 degree water running through it
So for example 38 pipe runs with the pipe running in ladder runs would have 7,600 feet of one inch pipe that would or could be split amoung the eight boilers with each boiler heating 950 feet of pipe fully exposed to the snow and melt water
