    A cleaner wood fired boiler

    Hi; Thanks for your reply I haven't seen any wood burners actually have a catylic converter. I also never thought of incorperating an automotive catylic converter for that use in a wood fired boiler. I was planning on the superheated secondary supply air to "breathe" on the converter and have...

    A cleaner wood fired boiler

    Hi: Thanks for responding! I'm looking for better more complete combustion. Secondary combustion air in the Switzer boiler is not preheated and no seperate chamber. I was planning on lining the fire box with fire brick leaving a gap between the brick and the water jacket. Secondary...

    Multi-Effect Heat-Pumps or MEHP

    Hi Durtydan I have heard of 2 Carrier attempts at home heating. I never heard of this problem from the system you mentioned. Just what caused the leak? The other system had a natural gas engine to run the compressor for a co-generation heating and deamed too complex. Have you seen them...

    lube for propane refrigerant

    What kind of oil is best for use with an open (shaft driven) compressor to be used in northen climates. It is expected to run between 300 and 800 rpm's for refrigerator room and reach in freezer. Thanks Drkillroy

    A cleaner wood fired boiler

    Hi: I am looking for info on how to design a better boiler. I don't know which is the best forum to post my questions. The system is built by Switzer. It is company a short distance from my home builds wood fired boilers for residential heating. I believe I can make some improvements over...

    Resistance on heat sink fins???

    WOW!!!! What fluid with a low freezing point (near 0 degrees F.) that can conduct and carry a large quantity of heat per pound mass can be used that is not reactive with copper and aluminum (not in direct contact) within the same system? I'm mentioning copper as well to cover other potential...

    Limitations on Tractor/Combine Design

    Slugger926 "Smart Sprayers" Tell me more about the way they work? Years ago I heard of mounting microphones next to the nozzle to send an alarm if the sound of the spray changes! What else is going on? Drkillroy

    Limitations on Tractor/Combine Design

    I do have anbother question along the same subject. I have read about low flying air plains that fly just above the water and are capable of carring heavy payloads. I read the military want them for moving tanks faster than a ship for rapid deployment. Would the same principle work over land...

    Resistance on heat sink fins???

    Hi there! I'm courious about reactions between the heat sink and the fluid used to transfer heat. Plastic would, I believe, be much less reactive than aluminum. Automotive applications see white powder corrosion even related to the cooling system running antifreeze. Also a jell of some...

    Limitations on Tractor/Combine Design

    Concerning tractor/ground mode going 15 to 20 mph is road speed. I bale at 3 MPH, plow at 4 to 5 MPH, and final fitting, conditions permitting, at up to a blazing 8 MPH. Knife sections are about 2.5 inches deep and must move the width of the knife section (about 3 inches) before changeing...

    pressure and temperature change with amonia

    I am tring to figure what would take place in a cylindrical chamber under about 600 PSI amonia vapor refrigerant at about 180 degrees F. A small amount of hydrogen vapor is then injected into the chamber. Will this cause the temperature and pressure to decrease? If so, how do I calculate the...

    Resistance on heat sink fins???

    Pzas I'm confused here. There is a heat source that needs to be cooled. A fluid is going to be the medium used to transfer the heat from the source to elsewhere. Wasn't teh origional question asking wheather plastic heat sinks could conduct the heat from the source to the fluid almost as...

    Limitations on Tractor/Combine Design

    Your idea does address another issue farmers experience. Transportation of equipment to and from the fields. The equipment has to fold up, sometimes several times, to become compact enough to transport on to roads to get to the field. Some equipment is transported sideways until ready for...

    pressure & state change

    An amonia absorbtion refrigeration system uses nitrogen to cause a temperature change in the evaperator. If an amonia gas is trapped in a chamber at normal system pressure, then nitrogen is injected, will there be total pressure decrease within that chamber? External chamber temperature will...

    battery efficiency (rechargeable)

    I have a question about batteries and the amount of power consumed by charging them vs. their power output. Is their some kind of listing somewhere of battery characteristics to compare energy storage efficiency? Is there one that includes battery weight to results? I want to know about...
