How they get rid of snow in Hokkaido

[leonz]

So, $1.5 billion for Boston, plus 5 million per snow event to run it (if you can get the EPA to clear it) and then you still have to put the meltwater somewhere and filter the nasties out of it. They do it there because they don't have space to pile they snow and they regularly get feet of snow at a time.

Boston generally has enough space to dump the snow and it generally warms up enough for it to melt down during the winter.

Also, in step 9, they would test with water, not air. Less chance of problems if a line fails catastrophically that way.

The process list skipped right over the traffic study, along with the Enviornmental impact report.

Both of those should come in under the $10 million "Misc Costs" item. But don't count on it.

Also, 5 certified boiler engineers to keep the boilers running 24x7 during the winter and enough trucks to bring the snow there vs renting 2-5 semi truck sized melters that can sit over any clear stormdrain which can be run by most any fool with half a brain and can sit next to a snowpile so further trucking is not needed.

The installation cost would be much lower and the operating cost is lower
as coal is used to heat the water to melt the snow dumped in the tank
which has previously heated water in it which also has a huge amount
of heat energy in it to melt the snow and ice to begin with.

As long as the water in the melt tank is above freezing it will melt the
snow and ice.

A second air operated mud pump in the tank could be used to circulate the
melt water to aid in dissolving the snow and ice at the same time.

A small generator would be more than adequate to power the system and
would not not be subject to power failures from a snow storm.

The melt water would travel to one of the storage basins in Boston for storm
water to be pumped to Deer Island for treatment and then discharged to
the ocean outfall.

The mud pumps would pump the mud in sump pit out into a tanker truck
and the garbage in the pump sump can be pumped out by a large trash
pump that would pump the tank dry as it is flushed out with a fire hose
to clean it which is the way sewage sludge settling basins are cleaned in
sewage treatment plants.

Coal stokers like the Keystoker KG22 do not require certified, licensed boiler
engineers to operate them asthey are low pressure boilers
(minus 20 PSI hydronic water pressure )
(-15 pounds per square inch steam pressure).

I mentioned compressed air rather than water prior to commissioning
the system to make sure the gaskets seal properly as the Victaulic pipe
is used for high pressure air lines for air powered track drills and
jack leg drills as well.

The residential/commercial coal stoker boilers built by Keystoker are UL
and ASME and CSE certified and are fully automatic except for changing the ash tubs
or adjusting the timer and the stroke length of the pusher plate for adjusting
the coal volume delivered to the Pocono stokers fire bed.

The KG 22 is used for apartment houses with steam radiators, multiple hydronic heating loops and pumps, heating retail businesses, green houses using Modine radiators, commercial laundries for hot water etc., and they do not require tending or monitoring other than adjusting the combustion fan timers, emptying the ash baskets, or dumping oiled anthracite rice coal in the small hoppers that hold only 585 pounds of oiled rice coal.

The Keystokers have been sold and installed in the Bay State as well.

Doesn't the snow in Japan melt by itself now because of the radioactivity?

The navy yard I work at has a system something like the big yellow snow melter actually 2 hooked up to their own waste water treatment system . So it is nice and clean before being dumped back into the river.
