AK type water boiler

"AK" type hot water boilers are modern, improved design thermal energy source that is intended for water boiling in private home's central heating systems with natural or forced circulation using firewood, coal, turf or wood chip briquettes. Regime of forced circulation does not allow using circulation pumps with working pressure more than 1.5 bar. Boilers are produced from welded steel plates. Fuel burn duration is up to 5 hours. Boiler consists of convective part, furnace, furnace bars and three doors. Upper door is intended for cleaning boiler's convection part to ensure economic operation of the boiler during whole exploitation time. Middle door is meant for firing the fuel but the lower-ones - to remove ashes and regulate traction. That is done with the help of traction regulator which is placed on the top of the boiler. When setting necessary temperature, traction regulator opens or closes air supply valve to ensure even and longer burning of the fuel on furnace bars. Necessary traction is achieved with the help of traction regulator. Reverse water is delivered to the lower rare part of the boiler. The water is discharged using cork in the rare part of the boiler. Feeding is arranged in boiler's upper part. Fume-gas flows out trough the passage located in the rare part of the boiler. Further trough external passage it is infused into the chimney.
To prevent boiler from limestone, water for the boiler should be prepared in appropriate water softening device.
Water for the boiler should fit following standards:
- carbonate solidity - not more than 0.7 mg-ekv/l;
- content of suspended particles - not more than 5 mg/l;
- pH - not less than 7.
