Equipment for manual blowdown, considered a part of the boiler and installed with the unit, usually consists of a take-off line, a quick-opening valve, and a shut-off valve. The take-off line is always located in the lowest part of the lowest boiler drum, where the greatest concentration of suspended solids should form.

combustion gases pass through the boiler. The combustion chamber is taken, as the first pass after which there may be one, two or three sets of fire-tubes. The most common boiler of this class is a three-pass unit with two sets of fire-tubes and with the exhaust gases exiting through the rear of the boiler. Stoker Fired Boiler
Use a surface pyrometer to check condensate line temperature surface downstream of trap while equipment is operating. This line should be slightly cooler than the steam line feeding the equipment. If it is lukewarm or cold, the trap is allowing condensate to pass through, probably because of a flooded float or worn out thermostatic element.
A boiler in which heat and gases of combustion pass through tubes surrounded by water. A piece of equipment not directly attached to the boiler that is required for the operation of the boiler. A boiler that has water directed through formed metal membrane tubes connected to upper and lower drums.
Boiler designs can be classiied in three main divisions – ire-tube boilers, water-tube boilers, and electric boilers. 184.108.40.206 Fire-Tube Boilers . Fire-tube boilers rely on hot gases circulating through the boiler inside tubes that are submerged in water (Figure 9.2.1). These gases usually make several passes through these tubes, thereby transferring
