Air umpan boiler atau Boiler Feed Water nantinya akan dipanaskan hingga menjadi steam.Karena di dalam boiler terjadi pemanasan harus diwaspdai adanya kandungan-kandungan mineral seperti ion Ca2+ dan Mg2+.Air yang banyak mengandung ion Ca2+ dan Mg2+ disebut sebagai air yang sadah (hard water).Ion-ion ini sangat berpengaruh pada kualitas air yang nantinya akan digunakan sebagai umpan boiler
The improper warm-up of a steam boiler is one of the most severe hardships a boiler must endure. Going through the cycle of start-up, operation, and shutdown for any boiler creates higher equipment stresses and, consequently, much more maintenance-type issues than continuous operation at maximum rated capacity.
Foster to Start-Up Large Biomass CFB in Finland Source: www.gulfoilandgas.com 5/26/2010, Location: Europe Foster Wheeler AG announced the successful start of commercial operation of a large-scale, 125 MWe (385 MWth), circulating fluidized-bed (CFB) boiler island delivered to Kaukaan Voima Oy, in Finland.
The "PowerFluid" type boilers will be installed at the company's locations in Taicang, Quanzhou, Yongxin, Chongqing, and Dongguan with start-up scheduled for the latter half of 2018. While the value of the order remains undisclosed, the deal marks the return of Andritz to the Chinese power boiler market after an absence of almost two decades.
The 4VT Steam Boiler from CFB Boilers fits the bill nicely, offering significant energy savings, low maintenance and an impressive start-up time of 10-15 minutes. This speed in reaching full pressure is essential for maximising working hours and therefore money-making potential for any laundry or dry cleaning business.

Clear intakes and exhaust vents. Check for deterioration and possible leaks.
In 2009 a 460MWe once-through supercritical (OTSC) CFB boiler designed and constructed by Foster Wheeler will start up. However, scaling up the technology further to 600-800MWe with net efficiency of 45-50% is needed to meet the future requirements of utility operators.
CFB Boiler Components Start Up Burners SUB Operation The boiler steam pressure control may be supported with start-up burners. This is possible when a start-up burner oil flow controller is set in remote mode and the oil master is capable to control the fire power of furnace. Typically oil gun and all other related devices like valves, ignition

The primary air supply for the CFB is higher in volume than that for the BFB; this is despite the fact that secondary air is also used to minimize NO x formation. For Fosterer Wheeler, the dominant supplier of CFB technology, this resulted in a change in the air nozzles at the base of the reactor. FW encountered problems with pluggage of bubble caps and, at first, went with a "pigtail" design.
