Description
The SUNROD CHS boiler for hot water has a unique pin tube extended
heating surface. The vertical cylindrical body consists of a
furnace and a convection part integrated with the drum. The furnace consists of a gas tight membrane wall. A number of
downcomer tubes connecting the drum to the ring header ensure good
natural circulation at all loads through the furnace tubes. The boiler is side-fired which makes the boiler very easy to
ventilate and gives an operation and maintenance friendly location
of the burner and its controls. The incoming system water is mixed into the boiler drum by means of
a spreader with nozzles. The hot water generation is practically
instant from start. The response from load variation is very fast. The boiler can be inspected on the water side through the manhole
in the pressure vessel and through the hand holes in the ring
header. On the gas side, the boiler can be inspected from the flue
gas box at the top of the boiler and from the furnace. The standard cleaning method is by water washing, which efficiently
restores the original boiler performance data. After cleaning, it
is possible to make a visual inspection of 100% of all the heating
surfaces, a very important advantage when trying to reach highest
possible efficiency during the boiler's entire lifetime. |
