Technical description: The boiler have a horizontally arranged welded structure with one radiated and two convective passes. The combustion cham-ber is a smooth fire tube and joining to that a water-cooled cylindrical return chamber placed in the boiler inside. The combustion products leave the combustion chamber through the convectional smoke tubes of the second pass into the front return chamber welded to the front end of the boiler. The smoke tubes of the third pass from those the smoke leave the boiler into the chimney during a flue-collector mounted to the boiler's back takes one's place over the smoke tubes of the second pass. One might to perform the boiler's water-side check and cleaning during the wash-out holes located at the both side of the boiler drum.
The boilers are - according to the order - delivered with appliances suitable for operation by permanent control or periodical control. The boilers are working with available burners for gas, light or heavy fuel oil. Term of delivery: The time of delivery is 1-3 monts counted from the order or signing a contrct, a negotiation is possible in case of pressing order. Warranty: he warranty is valid till 12 monts from the date of setting into service in 18 monts counted from the delivery which one should be changed according to the contract. |
