Q: i want to know what my boiler temperature in my my apartment is its only a 3 story apartment/house and the door locked hat should the temperature of a normal boiler should be for water
A hydronic boiler for heat will run roughly as follows: Standing cast-iron radiation: up to 130F Baseboard (Fin-tube) radiation: up to 180F For domestic hot water only - and depending on the application, 120F - 150F in a residential setting. The higher temperature if tempering valves are installed, as 150F water will scald nearly instantly. You should not get more than 115F +/- at the tap as even that will scald sensitive skin. 110F is generally considered a 'safe' operating temperature (at the tap).
Q: My boiler is building up pressure from 29 to 30 psi. I have drained water out of the air tank to bring the pressure back to 12 psi. The pressure continues to go back to a high number. Is my air tank shot and how do I fix my problem?
First your boiler is a GAIA 424/8 S or RS don't know the model off hand but most combes are very much alike. Don't know were you got Knightsbridge from. Your problem sounds like a diverter valve diaphragm at fault. With the central heating turned off, look at the valve unit (large brass block 3 large pipes and two small ) on one end is usually mounted a switch block (black in colour) that is actuated by a pin that is pushed out from the valve when the hot water tap is turned on, is this working if not then its the diaphragm. Using a small screwdriver gently operate the micro switch does the boiler fire up now. If yes then the electronics are OK.
Q: How does size of boiler relate to pressure?
Why not use a 50 cc two wheeler engine to drive an 80 ton Mach truck? It is horses for courses.
Q: The water content in the boiler is 180 kg. The connected electric heater is 20 kW. Temperature of the water in starting is 27 Deg C. The final steam pressure required is 85 PSI.
First you have to heat the water and the boiler. Since you say nothing about the boiler you have to neglect the boiler part. You need to look up in a steam table the enthalpy of saturated liquid and vapor at 85 psi (99.7 psia, probably 100 psia is close enough) and figure out how much it changed. The part I don't know is how you know how much liquid you have and how much vapor you have without knowing the volume of the boiler. The two most plausible assumptions you can make here is that the boiler volume will only be large enough to hold the saturated liquid or that it will be so large as to require all the water to be vapor to be able to get to 85 psi. I would guess that you need to convert it all to steam so use that. So you compute the change in enthalpy from water to steam for the whole 180 kg and divide by the power input to get time to get there. Make sure to keep track of the unit conversions between metric and English units.
Q: What kind of boiler?
Vertical boiler thermal efficiency and mechanized combustion problem is difficult to solve, and the furnace water-cooled degree, not suitable for burning low-quality coal, the current production is gradually reduced, but limited to low-pressure small capacity and environmental control and power supply is not normal to a small amount of application.
Q: I bought an electric egg boiler, which can boil upto 6 eggs at a time. The temperature at which it cooks those eggs is not mentioned.Is it safe? I mean, will it prevent salmonella poisoning? I will be eating hard boiled eggs not the runny ones.
The nice thing about cooking is that if the temp is not hot enough to cook the food...it's not going to at all. So if it can cook the egg to hard boiled, then it's managed to get the yolk to the 158 degree temp needed to firm the yolks. So if you can get a hard boiled egg out of that sucker...then it's done the job and heated the egg to the required temp.
Q: The previous owners never left a manual or anything and I can't find this info on the website or anywhere. I'd rather not call out a tech if I don't have to.
The water pressure on the gauge should be @ 12-15 psi.
Q: 3 element boiler drum level?
A three element boiler drum level control senses three variables (elements) which are used to control the water level in a boiler drum. These variables are A.) Level in the drum B.) Feed Flow rate into the drum C.) Steam Flow rate from the boiler. The combination of these three variables helps the automation determine how to best control the feed valve under all load conditions. For propulsion boilers which can rapidly change load the three element regulator is best (compared to a single or dual element) for the compensation of shrink and swell effects on drum level under rapid load changes.
Q: Please enlighten me, large-scale heating boiler size and heating area how to use it?
Generally, the output heat load of a ton of boiler is 600,000 kcal. Normally, in the very cold area of the north, the heating system is selected according to the standard of 100 kcal / square meter, that is, one ton of boiler can be heated by 6,000 square meters.
Q: suitable heater for a 30 psi model boiler ?
Model boilers are covered under Miniature Boiler Code having found widespread application. In the USA the Licensing authority is the ASME. The relevant Code is: ASME BPVC (Boiler and Pressure Vessel Code) B31.1, PTC 25, NQA-1 Miniature boilers have somewhat relaxed requirements when heat exchange surface is less than 20ft^2 Typical inputs are up to 10kW. A suitable heater will depend on the anticipated output rating.
