What is priming in the marine boiler?
Priming is a carryover of entrained water with the steam into the engines that affect the turbine blade, break cylinder heads, piston, valves.
Should steam radiator valves always be open?
Steam radiator valves should always be fully open, or fully closed. Steam enters the radiator from the boiler, and fills the radiator. The air vent shuts, having sensed moisture inside the radiator. The steam then cools, condenses to water, and drains from the radiator. If you leave a valve partially open, then the steam enters easily, because of the pressure. But, the water has a difficult time draining, so the radiator can collect it, and steals it from the furnace, which needs it for resupply.
Boiler works but no hot water?
Sounds like you have a bad zone valve or zone pump. There is either a pump, and the zones in the house have zone valves, or each zone has it own pump. Zone valves go bad all the time, you can just replace the motor on it instead of sweating the new valve in. The box that is on top of the valve.
How does the valves work?
Venal bloodflow is at relatively low pressure, relative to that of the arteries. Because of this, there is always the risk of blood flowing in the opposite direction. This is where valves come in - they prevent the backflow of blood in the veins.
What safety measures should do by boiler tender during his watch?
The first and most important thing the operator must do at the start of his watch is to check the true water level in the boiler. This is done by first blowing down the water column, then blowing down the gage glass, remembering to close the gage cocks individually and reopening them to the proper position. Next he should check with the previous operator and check the log books for any known problems. Checking the safety valves, bottom blowing the boiler, testing chemistry of the water, checking safety cutoffs, and blowing soot off the tubes are all regular shift operations that must be done to maintain a safe operating condition of the boiler. Also, cleaning the boiler room is very important and shouldn't be overlooked, more operators are injured by slips and trips than any other hazard.
When inspecting a boiler is it true always test the air bleed valves on the radiators?
Yeah. sure, why not?
When inspecting a boiler should you always test the air bleed valves in the radiators?
It's the pressure relief valves you always check. We wouldn't want that nasty old boiler to blow up and hurt someone, now, would we?
Why must check the valves when startup the boiler?
To ensure proper functioning of the valve so that the boiler can operate properly.
Why does your central heating system radiators at the bottom of the house sometimes stay cold when the upstairs are warm?
On/Off valves in radiators turned off or clogged Another possibility is an air bubble in the loop that services the radiators that are not heating. Correction is to bleed the loop.
How do you stop your upstairs radiators coming on when you only put on the hot water system?
turn valves off at up stairs heaters
Is it OK to replace hotcold valves for laundry washer with Comp Boiler Drain valves?
YUP Just make sure there is an air gap in the washing machine
Which valves are exhaust and which are intake valves on Honda 400ex?
Exhaust valves are always smaller.
While replacing the Egr valve do you take off the radiators?
Should not have to. EGR valves are usually a very simple bolt-off, bolt-on replacement.
If you have cast iron radiators that heat your home what is wrong with some of the upstairs radiators if they get half hot and some don't get hot at all?
Answer There might be air trapped in the radiator, try bleeding. It's usually a flow problem. If the valves on all of the radiators are wide open, the steam will flow through the path of least resistance, often leaving some of the radiators lacking for heat. Try turning down the flow on some of the hotter radiators. You will need to spend a little time adjusting the flow... assuming that you have flow adjusting valves on the radiators. These old cast iron radiators have sections that are bolted together. Each section has a gasket to keep the steam or hot water INSIDE the radiator. Of course these old radiators collect rust over the years unless you are very careful and scientific about your water chemistry (most folks are not). You probably have a plugged hole in one of the gaskets between the section of the radiator that is getting hot and the section that is not getting hot. This "cold" section is being bypassed and not receiving any flow.
Is boiler a closed system?
A boiler can be a closed system if you include the pipes it is connected to, but usually there are relief valves that will allow the escape of steam to protect against excess pressure and inlets that will allow adding liquid to the boiler to make up for fluid lost from the pressure valves. Also most boilers are imperfectly sealed so they leak a little bit. If you do not consider the attached piping, then a boiler would not be considered a closed system since it would be constantly sending out steam and receiving condensate in return.
What is a safety valve gag on a boiler?
A gagging tool is used on the water drum safety valves for the pressure setting. The safety valves are gagged one by one and the blow off presure is set for the other.
Difference between boiler mountings and accessories?
Boiler mountings are different fittings and devices which are necessary for the operation and safety of a boiler .e.g. pressure gauge, safety valves , steam stop valve etc Normally these device are mounted over boiler shell .Boiler Accessories are auxilary plants or parts required for steam boilers for their proper operation and to increase efficiency of the boiler .e.g.feed pumps, super heater , economiser etc
