Some larger boilers have a 2, or 3-stage burner, but this is usually controlled by pressure from a Vaporstat. On a call for heat, the burner is on full fire, and when the pressure rises to maybe 4 ounces, the Vaporstat will either make or break a circuit, causing the burner to go to low fire to maintain that pressure, and not exceed it. Short
Pada umumnya komponen-komponen mesin bekerja di bawah pembebanan berulang (cyclic loading). boiler and other equipment from pressures exceeding their design pressure by more that a fixed predetermined amount. low flow rate safety systems. • Heating control: flow constraints of the fuel at outlet temperature. 5.

What must be done when starting up a cold boiler with a high-low firing rate control? Must be limited to low fire until sufficient warming so the boiler doesn't warm up too fast on high fire and cause thermal expansion and excessive stress on the boiler. 61 terms. kts231.
(b) On the boiler or boilers in service supplying steam to the main steam line and turbo-generator to which the incoming boiler is to be cut in, gradually reduce the firing rate on the superheater side at a rate not to exceed 50 degrees F. every five minutes until the steam temperature has been reduced to approximately 600 degrees F. at the

Jun 06, 2011 · The calculated peak heat flux for oxy-firing, about 290,000 Btu/h/ft 2, is more than triple that for air-firing of about 80,000 Btu/h/ft 2. In the oxy-firing case the high heat flux and the small flue gas volume leads to the flue gas rapidly cooling and the FEGT becomes substantially below that of the air-firing case. Clearly the thermal condition of this illustrative oxy-coal firing design is not practicable in a …
