Question 417. Low Water In Boiler Drum Is Unsafe Because It May Result In Overheating Of Water Tubes In Furnace. Why It Is Unsafe To Have High Water Condition In Boiler Drum ? Answer : High drum level does not allow steam separation to be effective and some water can be carried over with steam which is not desirable for steam turbine. Question 418.Get Price
Sep 15, 2021 · Improper boiler startup or operation could result in damage to the boiler, exposure to hazardous materials, fires, or an explosion. If your boiler does not have startup instructions attached, check its user manual or look up a digital manual online with a keyword search for the boiler's make and model.Get Price

See Fig. 6 Boiler feed pump. Fig. 6 Boiler feed pump: Double-suction reactor feed pump made of cast iron. Cast pressure-retaining casing parts are increasingly replaced by forged parts. As an example, such a feed pump could be designed with a flow rate of about 4200 m3/h and a head of about 700 m at a rotational speed of 5300 rpm.Get Price
A special feature of the boiler house structure at Lethabo is its 82,6 m high concrete superstructure with its sliding-shutter building technique. This type of structure, already employed at Matla Power Station, compares very favourably in technical as well as cost terms with the more conventional steelwork structure.Get Price
The Africa Center II We will replace the building's original electric boiler with a new high efficiency gas-fired condensing boiler. This will also entail energy efficiency improvements like gas-fired make-up air heat and gas-fired domestic hot water. The 2 pipe loop that the boiler supplies is distributed to water-sourced heat pump units Get Price
Types of thermal energy. Almost all coal-fired power stations, petroleum, nuclear, geothermal, solar thermal electric, and waste incineration plants, as well as all natural gas power stations are thermal. Natural gas is frequently burned in gas turbines as well as boilers.The waste heat from a gas turbine, in the form of hot exhaust gas, can be used to raise steam by passing this gas …Get Price
100 % airtight solution to boiler penetration. Permits axial and lateral movement without causing high stresses in penetration pipe and boiler wall. Maintenance-free; Used in heat recovery steam generators (HRSGs).Get Price
