Tango Negro controller - controller settings, large combustion, not burning

    Hello

    For a month I have been using an eco-pea kiln for heating the house. Oven for coal mine 25 KW with "screw" feeder. Newly built house, closed, but without external insulation, only porotherm 25 brick, in the middle are already plaster tiles, prepared for painting. The furnace is used from 2007.

    At the time of finishing works there are used 10 radiators, rather small single, the two largest are double 120, the rest is a single max. 80 cm long. Radiators have throttled valves for adjustment. In addition, a floor-standing floor about 40 m2. For now, only central is activated without heating hot water.

    Tango negro driver. I do not know how to set up in a different way. At the beginning of the use I bought the cheapest eco-pea from the market. The furnace often extinguished itself, just the eco-pea was wet, now it has been dried a little earlier. It burned almost 50 kg per day at a furnace temperature of 50 degrees and the ash was a large bucket a day. The house is around 15 ~ 17 degrees with outdoor temperatures from -3 at night to 5 in the day.

    Currently I have been using better 27 KJ peas from the warehouse for a week. The four-way valve is set slightly in the "side of the radiators" after a few days of smoking there were large sinters on the hearth until it lifted the ring. The furnace reaches a much faster set temperature, it burns much better in the burner, the only thing I noticed is hard for him reach the temperature after the temperature drops during work, as it turns off the working time, the temperature goes up better and the furnace stands with elevated temperature. The pump is set in half for the second gear of four. Preset temperature 50 degrees. The furnace burns not much less because about 40 kg, it's probably too much. It seems to me that it did not burn coal. I have already cleaned the stove a few times, even there under the burner where there is a "chimney" from the fan.

    I am asking for advice on how to set up the controller and a 4-way valve to burn more coal and to burn less.

    Current furnace settings: Tango Negro model around 2007, I do not have a room controller, setting 50 degrees.

    PrA - feeder operation time - 8s
    PaU - feeder break time in working condition - 41s
    CdP - blower sustained in operation - 20 s
    PpO - the number of fuel feeds in maintenance - 6
    CoC - waiting time in maintenance - 21 min
    Ofs - blower speed in working condition 5
    Bpo - blower in maintenance 4

    Greetings.

    I know that there are no universal settings, but it would be good to base on something. Not one hour I "spent" in the boiler room over all this ... slowly I have enough ... Unfortunately, I do not live there every day the harder it is to set ... As for fuel, I doubt that now I bought dry fuel somewhere, I tried already in a few places "Krakow" and it's the same ...

    A house with a usable attic of about 200 m2. Height of the ground floor 2.85, attic height 2.65

    If I raise the temperature to, for example, 60 degrees, coal combustion will increase too. What will happen if I raise the temperature to 60 degrees but I turn the 4 way valve slightly towards the furnace return? Then the return will have a higher temperature the stove should not cool down any more, the radiators will only be slightly cooler so it should work? Burning should decrease a bit?

    Please send me some examples of checked settings, I will have something to "base" on

    greetings

    Combustion can be slightly reduced when the walls are heated. But 40 kg of coal 27 MJ / kg for a non-insulated house with an area 200 sq m at the temperatures you have given, it's probably the norm. Here you can look at the graph of energy demand for an insulated house with an area 200 sq m. Https://www.elektroda.pl/rtvforum/viewtopic.php?p=16860979#16860979

    Maybe so, but at the moment, when there are no paintings I do not need as much as 17 degrees, there would be enough 10 in the house, and I would prefer that burning coal would be smaller, I do not live there ;) Is it possible to add a room controller to this Tango Negro controller? I looked at the back of the driver there is no such input ..

    Is what I wrote earlier about to change the valve more towards returning to the furnace reduce coal burning?

    As you lower the temperature of the water going out to the radiators, you reduce the energy consumption for heating, then the consumption of coal should fall. The problem may be the operation of the boiler at too low power, for example, as it externally is 10 degrees Celsius. :D

    If you have the option, try to reduce the temperature of the water leaving the radiators, at a constant temperature on the boiler, eg 60 degrees. Such operation may also require changing settings in the controller, because then the energy demand will decrease.

    As for the fuel you are right, I hear also from other users with worse and worse fuel. The house is definitely not warmed up. The house is on a hill around it is empty, it probably also gives you a blow by the wind.

    Simar boiler with a screw feeder, tango negro controller all from 2007. in the back there is no way out for a room controller.


    Today I changed my mind a little, gave too little fuel because it burned at the end of the day at the bottom of the burner and could not reach the temperature by this.

    I am thinking about putting on thermostats for each radiator and adjust them for 2 or 3 because they go to full power.

    It will also analyze the given page by you.

    Can large combustion also be caused by the fact that the boiler is more powerful than it should be?
    This one has 25 Kw and the project is 17 Kw. The house volume is about 850 m3

    Demand in the project was calculated for the insulated house. Now that you have it uninsulated and the 25 kW boiler works at 50% of maximum power, the efficiency of combustion is not much worse. What else, if you reduced the heating temperature to 10 degrees, the boiler would work at 25% power and often in maintenance, combustion efficiency would drop. The same situation can occur after home insulation. If you intend to continuously smoke in a fuel boiler, you should not oversize the boiler. I advise you once again when replacing the boiler to determine the required power, because according to me 17 kW in a project for 200 sq m of an insulated house, unless it is too much ...
