    Default For lack of a gas section, I'll post this here - LNG


    Liquefied Natural Gas

    It is on the horizon to be more common in the very near future.

    It has been coming, but it is like that distance train you hear so much about ... it gradually gets bigger and bigger and bigger and then ... then it's moving so fast that it rumbles over you if you are not ready.

    It's been coming for 15 years or so, but its storage and transportation are being worked out with much vigor and is now getting bigger on the horizon faster than it has before.

    Maybe Bob H. will see this and comment on it and its uses and compare it to LPG (Propane) and NG (natural gas).

    The gubbermint authorized the gas appliance industry to conduct compatibility studies on LNG with NG appliances. Miraculously, they found very little problem with compatibility even though LNG typically has a higher BTU/ volume content as measured by the Wobbe Index. Now, each appliance goes through its certification, such as ANSI Z21.47 for warm air furnaces with specific gases. In the case of NG, they specify the vapor density or specific gravity to ensure the BTU/ unit volume content. All their tests get thrown out the window with LNG. When you read a rating plate on a furnace, that BTU input and output rating, efficiency, temp. rise and warranty all become bogus. So, this is getting rammed down our throats. I first made the Hearth, Patio, and BBQ Assn. Technical Cmte. in 2005. The members who ran the listing agencies all agreed it was a major problem and the units would need to be converted to LNG then tested and listed for that application.

    It is all getting swept under the rug. As individual problems arise, the technicians, companies and homeowner will be left to deal with it.

    Now, understand that during peak loads, utilities will practice "peak shaving" where they spike the gas with anything combustible laying on the shelves so to speak. This may include butane, propane, iso-butane, ethane, and, now LNG. So, you'll never know when it is being blended in with your NG but an appliance may experience problems short term then go back to behaving. Welcome to the jungle!

    Keep the fire in the fireplace.

    Thanks Bob. It's nice to know our gubbermint is looking out for our best interests and not cowering to big business. I feel safer just knowing this.
