2. Recognize the purpose, function and operation of the following offgas system major components: a. Condenser air removal (CAR) pumps the nuclear boiler. Before condenser vacuum is established the main turbine is placed on turning gear and Figure 8.1-1 while a system schematic …
In this type of condenser, the suction pipe end of the air extraction pump is placed in the center of the tubes which results in the radial flow of the steam. It ensures better contact between the outer surface of the tubes and steam. iii. Evaporative Condenser: Figure 4.22 shows the schematic diagram of an evaporative condenser.
superheating the steam in the boiler and condensing it completely in the condenser. This cycle that results is the Rankine cycle, which is the ideal cycle for vapor power plants. The construct of power plant and T-s diagram is shown in Figures 2.2(a) and (b). (a) 2 q (b) Figure 2.2 : Rankine Cycle 1 4 3 2 T s 4 3 T 2 s Boiler Turbi ne Condenser
Aug 10, 2017 · The Boiling Water Reactor (BWR) BWRs actually boil the water. In both types, water is converted to steam, and then recycled back into water by a part called the condenser, to be used again in the heat process. Since radioactive materials can be dangerous, nuclear power plants have many safety systems to protect workers, the public, and the
temperature (EWT) and a 100˚F (55˚C) temperature rise (delta-T) to produce a boiler leaving water temperature (LWT) of 180˚F (82˚C). Condensing boiler performance is dominated by the boiler EWT. Figure 1 below shows a typical condensing boiler efficiency curve from a manufacture and a theoretical performance curve.
Tim Smith from Hudson Valley Community College discusses specific concepts found on a two stage heating and cooling wiring diagram. Tim uses the interactive
In conventional boilers, such as the one in the above diagram, the flue gases leaving the boiler must be in excess of 100°C in order that the flue gas does not condense inside the boiler or flue and corrode the boiler. Unfortunately, this means that a quantity of heat must be wasted in order for the boiler …
The heat from the condenser is conveyed to the cooling tower by the condenser water. Finally, outside air is drawn across the cooling tower, removing the heat from the water through the process of evaporation. The figure below provides a conceptual view of chilled water air-conditioning system with water-cooled condenser.

Boiler components. Deaerators/Condenser. Deaerator and condenser tanks are only used in steam boiler systems and not in hot water and hot oil boil because here the fluid always is on liquid form. The construction of these two types of tanks is almost identical, but as their names suggest, they are used for different purposes.
Alibaba.com offers 1,092 steam boiler ironing table products. A wide variety of steam boiler ironing table options are available to you, such as accessories, style, and board material.
the evaporator and condenser the heat transfer rates are given by the following expressions. in = m(h2 - h1) = T h S (Boiler) out = m(h3 - h4) = T c S (Condenser) T h is the boiler temperature and T c is the condenser temperature. The thermal efficiency may be found from the 1st. Law. th= 1 - out / in = 1 - …
A standard boiler gives off waste gases through a flue and into the atmosphere at a high temperature of over 200 degrees, where this is significantly reduced in a condensing boiler. The heat input is pretty much the same at about 250 to 350 degrees, but a condensing boiler has a much more efficient way of working compared to other types.
Steam generated by boiler with pressure and temperature is guided to do work on the turbine to provide mechanical power in the order of rotation. The former steam out of the turbine and then moved into the condenser to be frozen with cooling water that converted to water. Condensate water is then utilized again as boiler feed water.
