似乎城里供应天然气的的主管道（main feeder pipe）老化之后，很难挖掘替换，
所以容易引起天然气泄露。
文章说：有个研究还是波士顿大学和杜克大学一起做的， 说在华俯街上发现近6000个
泄露点，波士顿2012年则发现3356个泄露点，如果电线电缆地下井就在附近， 且有火
花或者断路发生， 那么就会引起爆
炸。
还提到波士顿， 芝加哥， 纽约有不少（老化的）铸铁管作为城市天然气主管道， 政
府数据说大量的off record天然气, 也就是说输出和输入不等时， 管道泄露点恐怕是
主要的导因了。

At >95% efficiency, burned clean nothing left.
-----------------------------
Myth: Heating oil produces many harmful air emissions.
Fact: Heating oil burns almost 95% cleaner than it did in 1970. Today,
residential oil burners produce less than one-third of one percent of total
U.S. particulate emissions. To gain even greater efficiency and lower
emissions, the industry, in coordination with state environmental agencies,
is working to cut the sulfur content of heating oil from 1,500 parts per
million to 15 parts per million by 2018. And, when ultra-low sulfur heating
oil is combined with renewable biofuels, you get the cleanest heating oil
available.
Myth: Heating oil is not renewable.
Fact: In addition to its sulfur reductions, the heating oil industry is
moving toward zero emissions with new fuel blends of heating oil and biofuel
, called Bioheat®, which contain between 2 and 20% renewable biodiesel.
When combined with biodiesel to create Bioheat® heating oil has the
potential to reduce emissions to the lowest level of any fossil fuel.

发帖数: 386 | 19 Reducing furnace noise?
I'm trying to cut down on the sound coming off our home furnace. I already
have the furnace room walls insulated with rockwool, which I find
insufficient. Short of adding more ...show more
Best Answer:
halfwittcg answered 7 years ago
It depends on what about the furnace unit is making the noise.
***Typically it is the fan motor***, or associated moving parts.
Sometimes it is the housing vibrating from the spinning of the blower fan.
It may be the plenum or metal (or other) box that the air blows through to
get to the ductwork.
Lets look at all reasons it can make noise and eliminate things
First, the fan. If the furnace/ac kicks on and there is a rattling or
grinding or whining or other noise that accelerates as the fan picksup speed
, the bearings in the fan blades or motor are going bad. This is not good/
expensive to fix maybe.
IF the noise is worse when the fan is at full speed and stays constant while
the unit is blowing air it could be that the belt is loose or if no belt
the linkage from motor to blower fan is loose or worn out. This may be
fixable with a little tinkering but not for someone not mechanically
inclined. The mounting for the motor or fan blower may be loose, try to
tighten the screws or bolts that hold them down.
If the noise starts slowly after the fan is at full speed it could be that
there is resistance in the plenum or ductwork/air ducts/vents. This usually
isn't that noisy, but it can be bad.
You should go throughout the house in each room and make sure that the ducts
are clear and vents are all open to the full. Usually there are fins that
direct the flow to a certain direction these should be open wide, also
behind them may be a flow restrictor fins. These are used typically with a
lever that opens or close the flow off completely to 'zone control' the room
. These should be open wide as can be too for the testing. Should be so the
air ducts and vents in each room are open wide and blowing air full when the
unit is operating. Be thorough as you search for vents in all rooms, you
may miss a vent or two in odd rooms, behind furniture or in larger rooms. If
any air vents are open wide and don't blow air with good force(should be
similar from vent to vent and from room to room, decreasing slightly the
farther from the furnace unit you get) then the ducts(tubes) are blocked
somehow. if they are in the attic, they may have been crushed by the cable
guy or the christmas ornaments box you shoved up there. or maybe you have
squirrels building nests within them or something ( similar in the basement
depending where the ductwork runs.)
If they are smashed, reshape as best you can and see if that gets the air
going again. (careful not to tear them open or cause leaks in the duct
itself) If too much air is restricted from coming through the ducts it can
make the unit more noisy. If the ducts leak into the attic or basement you
lose heat/cool into that space instead of the room and could cause water
damage from condensation. Seal leaks with duct tape or replace the duct.
Same goes for the return air intake(s) usually there is one at the furnace
unit on the door to the unit or an adjacent wall. The filter usually goes
there. the filter should be clean and fit properly for the opening so all
air goes through it not around the edges. Other return air ducts can be
placed throughout the house in larger homes so check that the same as the
air ducts and clear any blockages. Sometime when the unit is installed, the
unit is too powerful for the size of ductwork existing and this can
backpressure the unit causing excessive noise and resultant loss of
efficiency of the entire unit. It is working too hard to force air through
it. This is hard to calculate, a bigger plenum and more ductwork is required
.
Other major noise may be the plenum, duct work, vents or surrounding
wallboard or the floor where the unit sits may be loose and making vibration
noise that can be dampened by securing it properly/better... if it is
rattling or humming it may be the plenum or duct work. Tap on the plenum and
ducts to see how loose they are and if so, try to screw, rivit or tape the
parts that are noisey so they can't flex so much. This may dampen the sound
a bit.
Make sure that the floor under the unit is solid and doesn't have any
weakness at all.
Sometimes there is water damage from condensation or poorly braced for the
weight of the unit or other reasons that weakens the joists or flooring and
that can really make it noisy but not be obvious. unfortunately, this may be
an expensive or extensive job to fix but maybe worth the trouble if the
floor is damaged enough to break under the unit.
This should eliminate most of the noise of the unit that can be fixed.
Sometimes you just have a noisy unit. In that case, there are other things
to do to help quiet the environment of your living space.
If the furnace is in a wall that adjoins the bedroom or living areas, you
might try to place larger pieces of furniture infront of the area where it
is. Like putting your big dresser on that wall right where the furnace is
located. Maybe hang a tapestry on that wall as well will help quiet it some.
Move the bed or your sitting chair to the other side of the room from the
furnace.
Another more extensive fix can be to double up the drywall board around
where the furnace is to quiet it down. this seems radical, but it will
reduce a noisey unit significantly if done properly. (last resort stuff)
In short, Eliminate any vibration noise, air flow restriction noise, or
structural weakening, use sound barriers in the rooms or consider replacing
the furnace altogether.
An existing furnace that is over 5 years old (the pros say) is inefficient
and can cost up to 50% more in energy cost than a new unit.
A new unit can be much quieter, more efficient and sometimes you can move it
to another area that is less annoying noise-wise.
Hope this helps!
Good luck!

发帖数: 386 | 24 Will a carbon monoxide detector detect a gas leak in the house?
I notice a faint smell of gas in the house. Will a carbon monoxide detector
register a gas leak?
Best Answer
Chiefmanycrows answered 5 years ago
No, carbon monoxide and natural gas are two different things. Carbon
monoxide is produced when a hydrocarbon fuel is not combusted completely.
Natural gas is about 96% methane with a small amount of ethane mixed in. It
is a colorless and odorless gas. An odorant is added to it to give a garlic
like smell to it so you can detect leakage. If you suspect a natural gas
leak you should have a qualified service technician come in and perform a
leak test. It is fairly simple to do and will quite possibly save your life
or home. Natural gas is lighter than air and will rise. It can accumulate in
pockets beneath floors or ceilings. All it needs then is a spark or other
source of ignition. Often times a pilot light can be blown out and allow
small amounts of natural gas to build up. Over a few hours a large amount of
the gas can be released. Do not take this matter lightly, it can be
extremely dangerous if it is not taken care of.

said Klappa to Newsradio 620 WTMJ's Jonathan Green on the Green House.
Klappa's wife was sitting at the table when it happened.
"The whole house just blew. Everything in the house went.""
"It was a miracle that God didn't kill anybody, didn't have anybody badly
injured," said Prasad.

What kind of logic is that?
"It was a miracle" -definition: God didn't kill anybody, didn't have anybody
badly injured:-)
"We're really blessed" - definition: when your house blows up and wife ends
up in hospital and your cat is missing. :-)
With miracle and blessing like that, no wonder every day normal life is
getting tougher.

They can argue they're not liable to leakage inside the house, since they
refuse to do any gas work inside.
You can sue the "independent contractor", but rest assured he can't pay much
or will declare bankruptcy if you win in court.

Just caution people that natural gas is highly explosive, many don't have
slightest idea about that.

FIRE/SMOKE/CO DETECTOR 对Natural Gas 不工作。
装了专用的NATURAL GAS DETECTOR还要小心。 每年起火烧死人的房子按法律都应该装
