Steam Heating

Water pressure before umpeu must ensure receipt at the exit of her hot stream (from the loss of water pressure) with the required pressure of water mains. On the pumping effect of psa. In promotional materials, on psa, often stresses such property as an opportunity to heating and pressurizing the water network. There are allegations about the possibility to refuse pump (negative pressure drop). Expert opinion on this issue 3: 1.Ispolzovanie steam injector for heating the cold water steam and hot water in a storage container is possible if the water and steam in their characteristics comply with sanitary norms and rules. 2. usefulness of the steam injector system for training a network of water at consumer substations that are connected to the steam heating systems are not so obvious and should be considered for each object individually.

If the scheme of heating mains water will be used by psa, which combines the heating system water to increase its pressure, the hydraulic and thermal regimes of the thermal system with psa are interrelated. Dr. Hedvig Hricak describes an additional similar source. With increasing (decreasing) the outside air temperature required temperature of network water should decrease (increase) according to the temperature control schedule. This means that the flow of steam through nozzle psa should also decrease (increase), which leads to changes in network pressure hot water at the outlet of psa, and therefore will change its flow. In turn, due to variable water flow, the temperature at exit from the heating system is not equal to the values that should correspond to temperature profiles, calculated at constant flow of water mains.
