    Intora-firebird. H2O2 helicopter

    Reply to Graviman I dont think H2O2 is dangerous, certainly not when you compare it to conventional fuels or liq. oxygen etc, you simply have to handle with rubber gloves, wear the right coveralls etc, have plenty of water available to drench any splashes or leaks. But of course the engineering...

    Intora-firebird. H2O2 helicopter

    The H2o2 mix, no flame intended just far greater reaction in order to get more efficiency from the fuel, any flame would be a very bad point because the machine had to be radar proof, the problem with mixing is that when the 2 fuels meet within the swirling tubes they are at quite a high...

    Intora-firebird. H2O2 helicopter

    To Helidev. The scientists claimed that in theory the Intora-firebird could start a flight submerged under water and proceed to 20-30 thousand feet, well of course it was never attempted. The fuel consumption was the main problem with attempting extremes of any kind. And frankly all our...

    Intora-firebird. H2O2 helicopter

    Sorry I cant answer using the correct procedure, having probs with my pc or with the Eng-Tips site. Answer to VE1BL Your message difficult to understand, Re: Yes, real world testing. The Intora-firebird was tested on numerous occasions by a qualified test pilot. Mostly at Southend airport...

    Intora-firebird. H2O2 helicopter

    I was one of the engineers working on this project over the last few years. With regard to the fuel, it is certainly no more dangerous than conventional fuels. In fact much safer, you just mustnt let it come into contact with anything organic. But as a fuel it has much to offer. It's made from...

    Voranate, What is it ?

    Please advise We have a 45 gallon drum of chemical which we are told is dangerous, and we want to dispose of it, BUT we are not chemical engrs, we have no idea about these things. The label on the drum is as follows. VORANATE M220 - UN no 2489 ( Diphenylmethane 4 - 4 dysocyanite isomer /...

    Gas seperator / scrubber.

    Saxon. Many thanks for your reply. Unfortunately I am not a chemical engr. so I am struggling with some of the probs. Our incineration process is dealing with semi dried sewage. The scrubber water is returned to drainage system ( which just cant be right ). Regret I dont know the make up of the...

    Gas seperator/scrubber.

    To Carolina8 Many thanks, although I have to confess I didnt quite understand it. We will study your answer and hopefully the "light will come on". Are you in Carolina USA. I was there for a few months at Columbia, great place.

    Gas seperator/scrubber.

    We have a prototype high temp incinerator, the exhaust gas is urged along, at low pressure, by a vac pump which is way down stream in the cool area. When the gas leaves the incinerator it is at quite a high temp, approx 600 deg C. but as it cools down there is a tar like substance that settles...

    Engine that operates on waste heat or low quality fuels

    Further to my previous answer. This is actually old technology, its been brought up to date by STM, It was developed many years ago and was known as the STIRLING EXTERNAL COMBUSTION ENGINE look it up in your reference books or library, it makes fascinating reading. Certainly seems like a...

    Engine that operates on waste heat or low quality fuels

    We have a prototype V.high temp incinerator in operation and we are aware of this technology and we are in discussion with this company. regretably there are no units operating outside of the USA ( we are based in UK ) also the technology is very new. Certainly seems an idea worth considering...
