connecting coall stoker in conjunction with oil burner, details

Where can detailed instructions be found to connected a coal burning unit with a seperate oil butning unit?


  • More info needed


    That is an open question.

    Is it steam, hot water, warm air?

    One thing I can tell you up front is if it is not one unit LISTED for multi-fuel, then you will need 2 separate chimneys.

    You can not use a fuel oil unit and a coal unit both in the same chimney.

    interesting question -

    and combination of fuels. Depending on your jurisdiction this may or may not be feasible. That said - coal stokers and oil burners (number 2 or used oil) can be interlocked with the correct sequence of relays & temp controls to prevent both firing simultaneously. Its a popular combination for grain dryers. I would recommend you find a PLC guru and pose the question at his/her desk. Unless you are completely comfortable with commercial burner controls (and correctly trained); the complexity can be over whelming. Detailed information? That depends entirely on your selection of controls. This also brings up the issue of combustion air and chimney requirements - again some jurisdictions may allow this combination, others may not. In the combo burners I have seen - it was always the fire insurance carrier that had final word.

    Multi-fuel Boiler

    There is a multi-fuel boiler that is made to burn coal and oil. Are you using anthracite or bituminous coal? I am very fond of coal boilers. Today many of them are automated so that you do not have to shovel coal into them. Here is a link to a multi-fuel boiler:
