Profitec Pro 300 User Experience - Espresso Machine

2016-3-24 · My unit was 15A, 1600W. For those of you who have the 20A version, it could be faster. Initial ramp up was fast, about 3 mins to get to 190F (with steam boiler off), but it will take another 10 - 12 mins to stabilize at 200 F. Dealer said this is perfectly normal. This is fine, given the portafilter also needs time to warm up.

Increasing the flexibility of coal-fired power plan

2018-3-15 · steam temperature change in the turbine can be managed as the boiler is starting up and shutting down. This allows thermal stresses in the turbine to be reduced (Lindsay and Dragoon, 2010). This is not to be confused with another type of bypass (HP stage bypass), that can be installed for frequency control in new plants and is described later.

Electrode boilers and the energy transition - Moder

The boiler is bidding for secondary regulation, and when it operates, less gas and coal can be used for steam production. The electrode boiler at Leverkusen delivers saturated steam at 32 bar g, and the low voltage super heater brings the steam temperature up to 380°C. Also pictured (above right) is a 15 MW electrode boiler employed in a power

A guide to Night Steam with Hot Water - Factori

2016-10-15 · 33 steam engines in a row are normally a terribly bad idea. But it works here. During the day there's only the water flow from one shore pump, and sustaining that over a long-ish pipe is no problem. At night the first ten steam engines are supplied as normal, and for the other ones the water only has to flow 1.5 steam engines from a tank.

How to estimate the time it takes to generate stea

2019-5-14 · The main issues would be how fast the steam valve can actuate and how fast the flow increase reaches the turbine (propagating at more than 50m/s) vs the roatational inertia of the turbine and generator. Thermodynamically the boiler ramp-up has similar thermal inertia issues. I'll refer back to post #4 I see it as two questions.

OT: Gas vs Steam Turbine Warmup

2014-7-28 · I used to work at a steam only power plant. The gas turbines ramp up at startup very fast compared to the steamer and compared to the steamers at my former plant. I am hoping someone can explain to me why the gas turbines are able to ramp up so quickly vs steamers. And please don't say, "Because they are designed that way." I already know that.

steam boiler waterline is plummeting — Heating Help

steam waterline plummeting Happy short week, guys. My contractor customer and I have a Peerless G-LC-10-SU forced-draft steam boiler, set 12 PSIG to serve fancoils, HX's and more in a hospital, and its' waterline disappears alarmingly fast (20-30 seconds) as if the water is leaping up into the piping despite the header, risers and equalizer being the proper size and elevation and piped correctly.

Could steam power make a come back? - AR15.C

2018-11-7 · ETA: In relatively costant, slowly changing load applications (like power plants) steam turbines do pretty well. In applications that have widely varying load requirements steam just can't ramp up or down that fast. Also, pretty well is still not 70% efficiency.
