Regarding fire backup power supply
Thread Content
What are the available options for fire backup power? Which one is more economical? In addition to diesel engines, there are other prime movers for emergency power supplies. . .
Our company has two power supply lines, both of which are connected to the fire protection systems; if one line stops working, the other one is activated immediately. Actually, I think that although the two options are not cost-effective from an economic perspective, in the long run a single investment will benefit one for life.
Generally, there are two options: dual circuits or diesel generators.
Our company uses diesel generators
1) Dual-circuit power supply； 2) Liquid or gaseous fuel generator sets such as diesel or natural gas ； 3) EPS emergency power supply system ； 4) Direct drive of fire pumps using diesel, etc ； For reference
Are dual circuits equivalent to dual power supplies? An emergency generator is a diesel generator; it’s not the same as a diesel pump set, right? An emergency generator can be considered a source of power
The types I have come across are 1. Dual-circuit systems, which require significant investment. But it is more favored by safety supervision departments; in my opinion, it yields the best results. However, some safety assessment companies give owners incorrect advice by referring to the two lines coming from a substation as a dual circuit, which is wrong. 2. For diesel engines, it is important to note how long it takes from a power outage to when the diesel generator starts and begins to deliver power properly, as well as to ensure that safety requirements are met. 3. Diesel pumps are more direct than diesel generators in driving fire pumps. 4. EPS is relatively expensive and has limited power. I haven’t designed it.
