from the boiler at Port 1. This situation results in a lower temperature flow at T2 going to the system. The formula to calculate T2 is shown in the appendix on the back page. FROM BOILER TO BOILER FROM SYSTEM TO SYSTEM T 1 Q 1 T 4 Q 4 T 3 Q 3 T 2 Q 2 PORT 4 PORT 3 PORT 1 PORT 2 Flow Path #3: Flow in the primary circuit is greater than flow in the secondary circuit.
Five hundred is the constant for standard water properties at 60°F and it comes from multiplying the weight of one gallon of water at 60°F which is 8.33 pounds x 60 minutes (1 hour). The complete calculation is then: GPM = BTU/hr 8.33lb./gal x 60 min x ^t°F. The formula indicates a

Mixing occurs within the hydraulic separator. T2 = ()f4 −f1 T4 +(f1)T1 f4 ⎛ ⎝⎜ ⎞ ⎠⎟ The temperature returning to the boiler (T 3) can be calculated with: Where: T3 = temperature of fluid returned to boiler(s) (°F) f1 = flow rate entering from boiler(s) (gpm) f2, f4 = flow rate of distribution system (gpm) T1 = temperature of fluid entering from boiler (°F)
divided by the maximum possible flow rate for downstream domestic hot water outlets. In a heat network with HIUs the coincidence factor is alternatively expressed in terms of the primary flow necessary to achieve the domestic hot water requirements and used as part of the pipe sizing methodology for the heat network. 3.0.04 Communal heating
01/08/2016 · Based on the thermal calculations of furnace chamber and thermal- hydraulic calculations of heating surfaces, the following conclusions were drawn: the minimum velocity of water movement (by condition of boiling surface) at lifting movement of environment increases from 0.64 to 0.79 m/s; it increases from 1.14 to 1.38 m/s at down movement of environmental; the minimum water flow rate by the boiler in the basic mode (by condition of the surface boiling) increased from 887 t/h at the load of
