Contact water heater of cascade type: the cylindrical
case of the device has the double walls forming a water shirt. Water arrives on
disks of a cascade part of the device through apertures in diameter (1 mm in an
internal wall of a water shirt. The cascade part of the device is typed from a
number of the disks made of a sheet steel. In disks made apertures in diameter
of 1,7 mm with step of 10 mm. Through these apertures water flows down small streams
from a disk on a disk and heats up products of burning of gas. Along the edges
of the bottom disk apertures in diameter of 5,5 mm from which hotwater merges
in the ring receiver having a conic internal wall are made. Water streams fall
on a conic surface, instead of on a water mirror in the receiver, without causing
formation of splashes and by that protecting a fire chamber from water hit.
From the
receiver hot water merges on a pipe in an account tank if the device is established
on the top floor of a building, or moves in account tanks the pump if the device
is established below. did you see cheap cell phone cases from China . Look at PPC management right now! . aciphex The device fire chamber is equipped by injection torches for pressure. Products
of burning of gas leave in a chimney at the expense of natural draught. For protection
from corrosion device disks produce from stainless steel or aluminium. Diameter
of the device of 1200 mm, height of 3250 mm, weight of a metal part of 350 kg,
weight of a laying of 1000 kg. Device operating experience in 1956-1964 and the conducted tests have shown
that at thermal loading of 600 000 kcal/ch it is reached to. The item д. 90 %
(on the higher warmth of combustion of gas) or 100 % on the lowest warmth of combustion
at heating 10 t/h to 70 °C.
