Schmid AG wood-burning furnaces have intuitive operation - the Personal Touch visio control system. It guarantees optimal combustion conditions with high efficiencies. In addition to a modern design and high user-friendliness, the web technology HMTL5, the worldwide standard for modern web browsers, is in use.
The use of this technology results in versatile possibilities of how the firing systems can be operated. Four independent connections can be made simultaneously to the plant for operation via a smartphone, tablet or the built-in touch panel.

The temperature of the primary air used for combustion is of great importance for an energy-efficient combustion process. The use of a combustion air preheater makes it possible to reduce the nominal output to 15 % in controlled part-load operation.
Up to 900 kW nominal power and at a maximum fuel moisture of M 35, electric industrial hot air blowers are available for igniting the fuel in the firing pan or on the moving grate.
Boiler bypass for raising the exhaust gas temperature in startup and shutdown operation. This increases the filter availability.
The heat exchanger tubes are equipped with plug-in turbulators for the
lowering the exhaust gas temperature. This increases the
efficiency of the furnace is increased. In the case of frequent operation in partial or
the turbulators may have to be removed if there is no boiler bypass.
if no boiler bypass is available.
If one or both options are selected (boiler bypass and intermediate ceiling cleaning), the central pressure line is required as a pressure accumulator
required.
Three flow temperature ranges up to 115 °C, TÜV tested, are available for hot water boilers:
Regulierte Beimischung von Abgas in Primär- und Sekundärzonen zum Absenken der Rosttemperatur, der Gewährleistung des Ausbrandes beim Eintritt
der Sekundärluft und der Kühlung der Brennkammer. Empfehlenswert bei
Brennstoffen mit hohem Heizwert (<M30), bei tiefem Ascheschmelzpunkt
und in Kombination mit DeNox-Verfahren und Abgaskondensationsanlagen.
Continuous monitoring of the fuel water content is essential for constant operation of the combustion plant . The fuel water content is permanently recorded and, if necessary, the operating parameters of the combustion plant are automatically adjusted.

Benefit from our many years of experience and let our specialists advise you individually, without obligation and free of charge.
The UTSP visio plant operates on the principle of underfeed combustion. The pellets are fed from below into a combustion retort made of high-alloy cast iron. The complete combustion chamber is lined with refractory material and ensures a high firing temperature.
The primary air is fed through the cast bars in the combustion retort, where it produces a quiet gasification of the combustion material. The secondary air supplied in the combustion chamber ensures optimum burnout and thus low emission values. Ash removal takes place via a burnout grate. An ash screw is arranged under the burnout grate, with which the ash is conveyed directly into an ash bucket or into a container.
The firing unit is completely surrounded by the primary and secondary air and, together with the effective insulation, ensures minimal radiation. A well-dimensioned 3-pass flue tube boiler is mounted above the firing unit.
