  • Using hot water to run your still. Anyone using that

    Dec 04, 2015 · Here is what I am thinking.. Sounds like the hot water works much as I thought. I Think I would look into a water boiler powered by NG and not ELE. 120kw is about 409,500 btu's. That would be a cheap boiler to buy. About $4000-$5000. That sounds great.Learn More

  • Mathematical Modelling of Dynamics of Boiler Surfaces

    In the present work we propose a mathematical model for the simulation and design of the once-through boiler. The modelling approach used for the simulation of a conventional boiler has to be revised, since the heat transfer regime in each tube can not be fixed by the equipment design. General equations have to be used for each tube of the boiler.Learn More
