Preparing Steam Boiler For Start Up - 4th Class Power Engineers

[Music] foreign control valve and we float into the wood so I need someone to open that valve and that done okay and what kind of valve do you think those are Cape Town yeah those are data those are rising stem Gear cups so I want one guy there and one guy here and then let's let's all let's just open open the belt there's no pressure so there's no harm nothing can happen yeah fully open so one guy there and one guy one guy if you're a little sticky [Music] that's a rising stem gate belt and you can see as the as the stem comes out the gate will move up into the upper part of the body and the valve is open up you never you never leave these half open or half close or whatever a gate valve is either wide open this is our level of control this is our our manual level control boiler level control and it's in manual flow so that valve when we start the pump it won't all of a sudden put water so we always we always uh start with the valves everything's closed we're almost okay [Music] that soft water or any kind of water will hold oxygen CO2 gases and when you you put that in a boiler that gives you protein so you don't want any air going into the bush you want pure water soft water so this is called the Deering so you're you're removing the Air Generation and the way we do that is this valve here is bringing in steep so what happens is the steam will spray in there heats the water and when water is hot the gases will go up and then we've got a little vent and it's up there and you don't even see the air come off because there's we're talking minute amount of amount of hair but there is a little pipe that if there was there it just comes out let's let's actually go up there this unit is for boy or four so just forget about it it's identical to this one other than this one it's slightly larger the fastest way they are same pressure same temperature all that kind of good stuff so you can see the green line that's representing the water level if you actually look at the gauge glass it's a little dirty it's more or less maybe not exactly at that line that's where the metal should be so this vessel is um I would say you can say half full of water half full of steep so part is steep the bottom part is what water will leave the bottom go straight to the pumps pumps will pump it to the boiler and away we go this here is the steam coil that's that's easy so again put your hand anywhere up here and you can feel everyone feel it it's warm because the coil is keeping it at 109 degrees or 150 the whatever the computer is done so that way we can put hot water into the boiler right away so there's no shop or whatever the boiler is sitting at 100 degrees this water here is 100 degrees and Away people [Music] from the water the oxygen would cause erosion and CO2 would cause pain and then eventually together but basically it's removing the air from the water thank you all about the different type of stuff but we always check because you never know what could happen suction open discharge open safety valve is in place suction valve is open discharge valve is open safety valve is in place no leaks nothing like there's no bolts missing but I want one guy on each pump and I want you to open the orange handle valve and we're gonna prime the pump so one guy there one guy there and one guy it doesn't matter who because everyone's going to do it eventually and open that back foreign we're making sure it's full of water so is it full of water yes no yeah I think close it out so we're just making sure it's primed because remember these pumps or any kind of pump doesn't like the pump air it only likes to pump water so never prime the pump after it's running because first of all you need to prime it before you run it but if you were to open that valve when it's running then you have a pressure of 1200 KB not that's not cool okay let's go back now to the panel on Corner two and we'll see you guys can start click Start okay so you see the color change watch your pressures your pressures it's pumping it's starting to fill up and you can hear it 14 controller is not controlling the pressure 1200 so you start it and then I want you to send two guys over there to check the pump a man two guys you're the boss so you're looking for leaks you're looking for smoke you're looking for something that's not right [Music] so is it good okay good and you should always check everything you start so look at here you've got good pressure but the pressure there the level everything the water's not going anywhere because the water is not running so let's go back to the boil so look at here you've got pressure here you've got good pressure here now this open the valve is open control valve when the computer's closed and we're going to open the bypass I'm just showing you something okay what kind of what kind of valve is that [Music] we always use blow valves on bypass so I want you to open that one too so you hear them hear the water flowing remember the pressure of the Border zero and the pressure on the pump is 1200 so it's flowing into the wood oh so we only use the bypass in emergency we have a control valve and Power Engineers like to click buttons and open valves so we're going to open that belt so let's all go back to the computer here on that box which is the CV that's going to be the manual signal to the valve click on it and type in 25 25 inches five enter so it open again we're using the computer you can see the flow [Music] that's our flow the valve is open 25 now we're throwing what I want you guys now to watch engagement and tell me what's going on again the level should be rising everyone needs to watch there is it Rising slowly no [Music] and we're gonna we're gonna allow the water to go for one level between nothing or enough water the white line [Music] now is that what you wanted that not five yeah so there's a little white Mark there that we put you guys can see the white mark [Music] that one one two four five so as long as the levels in between four and five we're safe to start and even if we didn't add water we'd be able to still start because the computer always checks the level but this is sort of just the manual rewarding basics of getting started [Music] so again you can do everything manually with your hands or we can use the computer and that's that's the best way [Music] fantastic one of the screen was like a mile away in the control room you're not going to run to the boiler and open it run back and all that stuff okay so are you guys happy with the level foreign [Music] classes in period because that's that's we haven't gone to that one the gay classes are your what I say is your manual level this is the actual level in uh steam gun you see you see how with the with the markets if you draw a straight line across that's 50 of the mosquitoes and that's that's a normal level okay else we've got the air system we've got a couple Breakers couple switches the water system we've got a lot of valves over there that we never touched the only valves We Touch are over here there's two valves over there and now it's time for a stuck well what else do you think we need to check now to come over here remember this is just the beginning we're going to start you know we're not going to open we're not going to open than on the turkey okay because we're not we're going to make Steam but hardly anything because we're going to try this what we did with them we're gonna do it for everyone [Music] so we're actually not going to open the steam valve we're not going to open the vent valve we're not going to do anything up top so we won't bother okay now let's go to the control panel we're almost ready to start okay so what I like to do for startups is forget about this page we're going to go to boiler startup this is the this is the computer program that starts the boiler this is the actual boiler so when something happens I can point out and we're just going to just watch what happens so first of all look at we're here Auto vfd that's good the green light is on that's good the red light was on that means something's gone right the ESD to the ESB button is in so I'm gonna gonna push this just to show you what the alarm sound so be ready it's going to rain push that in foreign or something happens that's what it's going to sound like kind of thing and then you're going to push uh reset and then you're going to figure out what's wrong and when you look here what does that say [Music] system emergency shutdown because he pushed the button so pop the button out and Pop It Up thank you push now close um push close there but look it's still in so click up here so that goes to the alarm that's your active alarms and I want you to push acknowledge off try resets [Music] okay so hit clear we have to go through a reset and then a horn try acknowledge all again CO2 alarm is in that's because our CO2 system on the boiler we've got an issue so just forget about that alarm let's go back to main go back to Startup so now now we're off of Step Zero we're on step one which is startup push start so we push start nothing happened because we have to wait so everyone stand over here [Music] that's the freaking area [Music] Chicago [Music] so the fan started because the big doors so we need fresh air now go to the panel won't go back to the panel look at that the motor's starting the fan is starting now there's going to be a timer Washington [Music] and it's alive [Music] so the fan is slowing down because the program is controls everything I'm not doing anything okay look at step five is just keep watching step six now I wanted one to listen and watch here and watch here okay watch it guys okay the valve's open [Music] we got a fire fire okay so now everyone go to the back of the boiler [Music] tomorrow thank you [Music] steam drum level high [Music] ER and also too when you when you start heating up the water the water will expand more and the level because we have the shotgun if it goes too high in a second so now push close would not get close close so now we're at step eight how do we go to step nine so right now this down is open or Center down too big look at your name yet the valve is not open because you need to push that button right there so watch that button everyone watch that now Naruto foreign ER is on low fire we're in Step nine we've started the boy so someone go check that fire again because we'll put in a little more gas [Music] so what we're going to do now we're going to go opposite you're going to push stop this way you're going to push stop because we want to shut it down and then he's the next guy is it open good okay now a couple guys go check the boiler so now we're on minimum fire once you push stop and then you're going to close all them out shut the bump off and then the next stop okay push stop water down it's now in perch because we're merging out the gases foreign foreign [Music] [Music] and those things are pretty awesome because they give you a an indication if the valves open or closed right yeah yeah it's really handy from the operator [Music] if you're picking the pump out of the three you want to pick let's say okay up [Music] that's the gas valve jump 105. next one is right here [Music] good okay [Music] foreign [Music]
