    Monotube Flash Boiler Design

    https://www.freestandardsdownload.com › free-asme-standards-download Here is a source but you will have to search what you want. Now there is a way that is acceptable to test your system with the ASME procedure However it is a potential destructive test. You hydro the unit under question to...

    Monotube Flash Boiler Design

    I have taken the 16 hour ASME exam for a certified inspector and delt with many of the rules I have the following comments. 1. The ASME are American standards complied and written by engineers who have a broad and highly technical background. The committees that are formed by the engineers do...

    Monotube Flash Boiler Design

    The battery is an energy storage device not a heat engine. It does not work form a high temperature heat reservoir to a low temperature reservoir. The construct of a cycle with regards to heat engines is very specific. The word cycle has a different meaning.

    Monotube Flash Boiler Design

    Based on the laws of thermodynamics particularly the first law . The change in Heat = The change in Work done across a cycle is the scientific rule. So now matter how you cut it for every cycle this law holds. And its useful in predicting how the engine will perform. The carnot engine...

    Monotube Flash Boiler Design

    The Carnot cycle can be constructed for many different arrangements and fluids. Including an IC engine. The calculated engine efficiency will give you the maximum efficiency of a theoretically reversible engine. This is what the Carnot cycle answers what is the best efficiency you can get...

    Monotube Flash Boiler Design

    No dont have any pictures and the situation was an over pressure occurred due to an operational problem. Copper tubing can take surprisingly high pressures at low temperatures. And it would have normally been ok. But if you look at the limitations of brass valves you will get an idea of the...

    Monotube Flash Boiler Design

    The severity of failure and its rate depends on the operating pressure and temperature not the material. The material properties determine at what state failures occur. Steel boilers operate at much higher pressures and carry considerable more working fluid in them. I have seen copper tubing...

    Monotube Flash Boiler Design

    The 12000 lbs is a vector force . Each of the side wall joints must distribute its force across the available wall area. Calculate that area and divide by 24000 lbs since there will be two apposing static vectors which will yield 12 tons of force. Your bolts are technically called stays and...

    Monotube Flash Boiler Design

    You need to double the 12000 lbs to account for the other side of the disk. You can deduct the area from the supporting walls forming the walls of the spiral. Not sure how to handle the spiral walls because internally they will balance out except for those on the out side exposed to...

    Monotube Flash Boiler Design

    I believe steamchick is correct. Even ignoring the thermal expansion issue the flat plate design internal side pressure is going to be very high. Say a 8 inch diameter plate will have 50 square inches or 25,000 lbs of force on the side walls (given a 500 psi pressure )and this coupled with...

    Head gasket

    There are commercially available gasket punch sets ranging in size from 1/8 to 1-1/4 size or 1mm to 10 mm varying in costs from 25 to 75 dollars. Felpro also sells a variety of gasket materials to choose from. However be careful as one of the products I have has reinforced wires embedded in...

    Re: crooked core in cyl casting

    This is an obvious casting defect with both castings suffering from the same flaw. The core is out of position in the mold. I think they owe you a good casting. The only way to correct this is oversize the bore as another member suggested, if there is room to fit all the other bolt patterns...

    Ambitious ORC Turbine

    In general the stage is ahead of the nozzle blocks. These are designed to increase the velocity of the flow but there will be a penalty. The rotor blades are designed to accept the high velocity and extract momentum energy. It is pressure volume work. But you should also know there are two...

    My experience has been that the patent is the only protection you have. It depends upon the potential value of what you have. You or anybody else can not defend the intellectual property if a patent does not exist get that first and then go talk to investors. But here is the rub- I have seen...

    Thread Dial

    The four marks are used for an inch thread system based on even or odd thread combinations. A metric thread offers more combinations and requires a chart for the dial. You need the instruction or a chart to select when to put the half nuts in. ON a south bend metric lathe you not only need...

    If you publish your patent idea without the patent it will be considered open source and anyone can copy it. If you publish a book you can only get a copyright to the material you publish. You need to find a patent attorney. This will cost money. You can do the work yourself but there are...

    Tests of CDI Ignition Modules

    I am sorry you can not understand the mathematical proof presented. There are other proofs available in various texts if you like but you will have to do your own research. Pretty much done with this subject.

    Tests of CDI Ignition Modules

    Some clarity is in order here. The paper is a compilation of notes from a class and textbook. The reason for posting it was it contains the mathematical proof of where the energy is stored. It clearly states at the top of the notes HF.(high frequency) It is series of organized notes and is...
