PIEL® Hydrogen Generator
1. Iron sheet shearing (steel plates cutting)
Instead of propane gas, natural gas, acetylene gas and
so on as heat source to cut iron sheets, Hydrogen gas can be used.
i) Cutting speed to be much quicker by
approx. 30% or more
time to be much shorter by approx. 50% or more
iii) Cut finish to be much smoother
iv) Sludge left to the cut sheet to
be easily removed
v) Gas utility cost to be much
vi) CO2 gas emission to be far less
propane gas burns to produce enough heat to cut iron sheets, the propane gas
consumes almost 3-5 times volume oxygen. However, in the case of hydrogen, the
volume of oxygen to be consumed is the half of the hydrogen (2H2+O2=2H2O), thus
total consumption of oxygen can be far less. Therefore total cost of gases for
heating is much smaller.
ii) In addition, because the
cutting speed by H2 gas heating is quicker by approx. 30%, the oxygen to be
used for cutting (=cutting oxygen) can be less by approx. 30%. Thus, heating
gas and cutting oxygen both can be saved.
iii) Heat by hydrogen can be much
concentrated in comparison to those of other combustion gases such as propane,
natural gas and so on, thus only the place to be cut is being heated.
Therefore, mal-effects by the heat to other parts not to be cut are very small.
This can have a positive effect that sludge left to the cut sheet, if any, can
be easily removed because the sludge is not melted and glued to the cut sheet. In
addition, bent-over by hydrogen gas heat will be far less in comparison to
2. Blazing (soldering)
Instead of acetylene, propane and other combustion
gases to be used for blazing, Hydrogen gas can be used for better quality and
cheaper utility cost.
Hydrogen Generator produces Hydrogen and Oxygen separately on-site. When the
Hydrogen burns, the Oxygen produced can be used, thus no extra oxygen will be
required. Therefore, total gas cost can be much less.
ii) Because no combustion gas such as
acetylene is stocked in case of PIEL Hydrogen Generator, safety at the
production line will be dramatically enhanced. On the other hand, acetylene
gas, for example, can easily burst even in case the cylinder just fall down.
iii) Hydrogen will not produce CO2
gases when burns, thus is much friendly to environments.
3. Cooling material for shaft between turbine and
alternator at power plants
Electric Power Development Corporation in Japan has
adopted PIEL Hydrogen Generator to supply on-site 99.99% purity hydrogen gas to
main line of Matsushima Power Plant in Kyushu, which has an electricity
generating capacity of 500,000 kW or more. The hydrogen gas is being utilised
as the material to absorb heat to be produced when shaft rotates at the very
high speed, which connects turbine and alternator.
gas cost can be cheaper because the hydrogen is being produced on-site, which
does not require a long-distance transportation.
ii) Safety can be enhanced because
less amount of hydrogen gas is now stocked in cylinders at the site.
Under the current circumstances, it is very
difficult to stock electricity. If PIEL Hydrogen Generator is adopted ,
however, the electricity to be diminished can be saved in the shape of Hydrogen
gas after electrolysis process. Oxygen can be also available. Under the
proposed system, power plants can level their electricity production, thus the
power plant management will become more efficient. The stocked hydrogen can be
used to produce electricity again by fuel cell. In addition, the following
areas are to be expected as the fields of hydrogen gas usage:
i) Automobiles for both fuel cell and
combustion engine type (PIEL already has a line up of hydrogen gas combustion
ii) Toxic waste gas to be used on the
process of semi-conductor production, can be decomposed by hydrogen and oxygen
iii) Sludges and ashes which are left
after garbages are burnt, can be finally melted by hydrogen and oxygen burning
and will become almost 1/3-1/10 in quantity and almost no toxic ingredients. It
will help more effective use of dumping areas with much safety.
