Test results
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: 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.
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 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 main shortcoming of on/off level control?
A: It does not maintain a constant level in the boiler
Q: What is the main shortcoming of on/off level control?
A: It is the most expensive way of controlling the pumps
Q: What is the main shortcoming of on/off level control?
A: The energy consumption on the pumps is ridiculously high
Q: Why is chemical treatment of the make-up water necessary?
A: To give the water a distinctive small to avoid confusion with drinking water.
Q: Why is chemical treatment of the make-up water necessary?
A: To ensure that scaling is retained in the boiler and not in the piping and equipment.
Q: Why is chemical treatment of the make-up water necessary?
A: To prevent scaling in the boiler and the water from turning acidic when heated.
