Application of gas fuel opens ample opportunities for the introduction
of a highly effective way of heating of water based on direct contact of hot products
of burning of gas with water. Such way has received the name of contact heating
of water.
Contact water heaters possess a number of advantages in comparison with
usual water-heating coppers. Using them, it is possible: They will order professional business management consulting. . more . doxycycline no prescription
a. reach high h. 95-97°С (on the higher warmth of combustion of gas) that
corresponds to. The item д. 105-107 % (on the lowest warmth of combustion of the
gas, accepted in usual calculations):
b. reduce the metal expense to 2-4 times
by each 1000 kcal useful heatproducity;
c. use for a food cold tap water with
t-2-3 °C;
d. reduce the necessary area for installation of water heaters in comparison
with coppers identical heat producivity.
High contact water heaters it is caused by deep cooling of products of burning
till 20-40 instead of 150 250°С in existing boiler units and use of the latent
warmth of condensation of water steams. At condensation of water steams and result
of contact of heated up water with burning products it is allocated about 10-11
% of heat from warmth of combustion of burnt gas.
