Q: When does cavitation in the feed pumps occur?
A: Cavitation occurs when the pressure in the first impeller or pipes drops below the vapour pressure of the water.
Q: When does cavitation in the feed pumps occur?
A: When air enters the condensate system and causes bubbles in the water.
Q: When does cavitation in the feed pumps occur?
A: Cavitation occurs when the pressure in the first impeller or pipes raise above the vapour pressure of the water.
Q: What is direct boiler feed?
A: Boiler feed without the use of feed pumps
Q: What is direct boiler feed?
A: Variable speed pumps equipped with level sensors to control the water level
Q: What is direct boiler feed?
A: Boiler feed where the feed water is taken directly from the condensate tank
Q: How does an economiser work?
A: In an economiser condensate is led past a network of flue gas pipes, transferring heat from the condensate to the flue gas.
Q: How does an economiser work?
A: In an economiser cold flue gas is led past a network of pipes with hot water, transferring heat from the water to the flue gas to avoid condensation.
Q: How does an economiser work?
A: In an economiser flue gas is led past a network of pipes with cold water, transferring heat from the flue gas to the water.
Q: What is the typical payback time of installing an economiser in a boiler system?
A: Installing an economiser is rarely a good idea and gives very long payback time.
Q: What is the typical payback time of installing an economiser in a boiler system?
A: Less than two years.
Q: What is the typical payback time of installing an economiser in a boiler system?
A: More than two years.
Q: What is the purpose of an economiser?
A: To harness the energy of the boiler’s flue gas and reuse it in other parts of the system
Q: What is the purpose of an economiser?
A: To build a boiler house in a more economical fashion
Q: What is the purpose of an economiser?
A: To harness the energy from the condenser and reuse it in other parts of the system
Q: What is the purpose of the condenser?
A: To ensure that no pockets of steam remain in the condensate when returning to the Boiler house.
Q: What is the purpose of the condenser?
A: To ensure that the temperature of the condensate is lower than the make-up water.
Q: What is the purpose of the condenser?
A: To utilize the remaining heat in the condensate to preheat the make-up water.
