SUBSTANCE: invention relates to boiler with smoke tubes. Boiler comprises mixing chamber located on combustion chamber and having space for mixing, in which combustion gas and air are mixed, and flat-plate burner is mixed. Unit of ignition electrodes is made with possibility of passage through one side section of mixing chamber for further assembly and passage in direction downwards from burner of flat-plate type along upper section of combustion chamber. Sealing device is configured to block leakage of the gas mixture from the mixing space and the combustion gas from the combustion chamber to the outside through the gap between the mixing chamber and the ignition electrode assembly.
