Solid propellant boilers of a series of Eu on the basis of gas - generating fire chambers are intended for use for heating, hot water supply, and also for technological needs.
The copper consists of a fire chamber and the water pipe heat exchanger.
gas - generating, nonmechanized, it is equipped with the operational fuel bunker with single loading for one hour of continuous work.
it is made of 3 concentric coils and the top cooled cover. The scheme of the heat exchanger, double - thread on gases, gives the minimum sedimentation of ashes on heat exchange surfaces.
The fire chamber of a copper allows to burn the following types of fuel: sawdust, shaving, wood spill, sunflower pod, waste of a chipboard, DVP, MDF, etc. Fuel also may contain scraps of a woodworking (up to 0,5 m long) to 30% on volume. Rated thermal power is reached at humidity of fuel no more than 30% .
The main requirements to fuel — an ash - content are not higher than 5% , humidity no more than 55% (122% ).
Calculation of humidity of W was made on formulas W=(mт - mс)/mт×100 by % , (W=(mт - mс)/mс×100% ) where mt — the lump of fuel, mc — the mass of solid in fuel.
