Q: What is the farmula of measuring Horse Power of a steam boiler by its heating surface?
*Boiler horsepower is used rating a boiler's capacity to deliver steam to a steam engine. The amount of energy needed to produce 34.5 pounds (15.65 kg) of steam, per hour, at a pressure and temperature of 0 Psig (0 bar) and 212 oF (100 oC), with feed water at 0 Psig and 212 oF. One boiler horsepower is about 33,479 Btu per hour (about 9,810 watts, 8430 Kcal/Hr). Boiler horsepower can be determined from the heat transfer area. PBoHP = A / 17 where, PBoHP = boiler horsepower A = heat transfer area (ft^2) *In a water-tube boiler there should be from 10 to 12 square feet of heating surface for one horse-power; in a tubular boiler 14 to 18 square feet of heating surface for one horse-power; in a flue boiler 8 to 12 square feet of heating surface for one horse-power; a plain cylinder boiler should have from 6 to 10 square feet of heating surface for one horse-power; a locomotive boiler should have 12 to 16 square feet of heating surface for one horsepower; a vertical boiler should have from 15 to 20 square feet of heating surface for one horse-power. When considering the heating surface of a boiler, a vertical or upright surface has only one-half the evaporative value of a horizontal surface above the flamet; that is, the sides of a locomotive fire-box are only half as effective per square foot as the flat top of the box. In flues and tubes, the effective surface, measured on the circumference, is 1% times the diameter.
Q: I asked this question once already, but I guess I didn't give enough info, so I am going to try this again. Bare with me because I honestly don't know anything about this, that is why I'm trying to get info on here. I am currently looking at buying a house that is heated with a boiler furnace. There are base board vents through out the house, and multiple thermostats to control the heating in the different zones of the house. I'm not sure if this also controls the hot water, or if there is a seperate hot water heater. My understanding is that there are lines that run along the base boards, hot water runs through them and some how heats the house?!?! Like I said, I really don't know, and I am just trying to get a better understanding of this system. ANY info on them would be much appriciated, such as cost to replace them, repair them, or service them. Common problems to watch out for, how they opperate, and if it would be better than a regular furnace.
Don't buy the house!!! My father owns a heating a cooling business and I helped replace a home such as the one you are considering to buy with a regular furnace. Major costs and house repairs!!!
Q: Anyone knows what would be appropriate combi boiler configuration (type/model/number of units) to provide heat for 3000 sq ft home? I am planning to have one zone for the first floor, one zone for basement and 4 zones (one for each room) on second floor.Thanks.
Your best bet would to sit down with an installer. You can have as many boilers you want to heat your house, but would it be cost effective. You can split the upstairs with the downstairs. (basement, first floor) on one boiler, and second floor on the other. I've been in the heating Business for 32 yrs, and only seen a few houses with two boilers. Personally, I would just go with one boiler, and zone off the rooms/levels.
Q: i recently installed a Kerr wood boiler in my house. I used it for 40 days to date. My last electric bill came and the bill was 40 dollars higher than the previous months. was wonderin if wood boilers use much electricity?
Depends, does electricity exist? If so, we'd probably use high compression steam or other gas to power many things. However, the Internet, tv, and fm Radio would not exist. Surprisingly, am and shortwave radio would work, if radioactive diodes were used. If electriciy simply didn't exist, life would be totally changed. Life would not exist. Everything would be A mass of random protons and neutrons, the universe would look pike a giant could, however, light and such wouldn't exist either, so nothing would be visiable. In short, we'd have universe soup.
Q: Boiler check first or external inspection first
For those boilers that can not be tested internally, a hydraulic test shall be carried out every three times.
Q: I plan to bleed my radiators for the first time. I've read that If you have a gravity filled system the system will look after itself but if you have a combi boiler, the pressure will need to be checked after bleeding. How do I know what I have? The boiler is an HB Smith G200 Series that is about 30 yrs old. Thanks.
-Combi boiler usually heat the hot water also. So they heat the house serve as the hot water tank. - Gravity filled are just plan steam systems. All your boiler does is heat the radiators. Combi systems PSI usely goes upto 30-40 Gravity systems PSI
Q: I found this recipe on food network, but ti calls for me to use a double boiler to create a frosting.. Must i use the double boiler? Or could i just put the ingredients into a stand mixer and whip it? Would it work just as fine? Please let me know asap!
So you don't burn or scorch the food.
Q: An iron boiler of mass 150 kg contains 590 kg of water at 12 degrees Celcius. A heater supplies energy at the rate of 9.7×104 kJ/h.a) How long does it take for the water to reach the boiling point?b) How long does it take for the water to all have changed to steam (including the time to reach the boiling point)?
Let's transfer some heat!!! Concepts: heat is in constant flux. It moves in the direction of lower temperature. In order to heat up the entire system (iron boiler and water) to the point at which each additional kilojoule into the system generates a unit mass of steam, you'll have to heat up the metal and water to the saturation boiling point. In Celsius, that's 100 degrees. Since you didn't mention it in the problem, are we neglecting to calculate the required energy to heat up the boiler to the same temperature as the boiling point of water? I'll have to assume both cases and give you two different times. You need heat capacities of the iron and the water: iron = 0.45 J / g / K, and water is 4.2 J / g / K You also need a heat rate. You're given that. Okay so let's take the iron boiler and the water separate and calculate two different duties. Heating up the metal to the boiling point of water: 150,000 grams iron * 0.45 J / g / K * ( 100 -12 K) = 5,940,000 Joules 590,000 grams water * 4.2 J / g / K * (100 - 12 K) = 218,064,000 Joules What's going to happen is that the heater will heat up the water to 100 degrees and at the same time the metal. Both bodies will have to be at 100 degrees before steam is being produced. Now: you need time; you have the rate; divide the duties by the rate to get time. 5,940 kilojoules / 97,000 kJ / h = 0.061 hours 218,064 kilojoules / 97,000 kJ / h = 2.24 hours Roughly 2 hours and 19 minutes to make steam!
Q: Please enlighten me, large-scale heating boiler size and heating area how to use it?
Return water pipe back to the boiler room after heating again after the output, again and again.
Q: The other day I came home to the boiler not working. The light for the on-switch was off, but the switch was on. I checked the fuses for the house; they were all ok. It was the fuse in the switch. So I changed it (twice), and both times I changed it, it blew the moment I pressed the on-switch. I used a 3amp fuse both times, because the original fuse was 3amp, so it's not that ampage that's the problem. Any ideas?
Find the manufacturer's installation instructions and check the wiring and fuse requirement, 3 amp does not sound right. If it is then there is a short circuit somewhere in the wiring of the boiler or going to it. You will need a qualified technician to repair this problem. The boiler may still be under warranty, call the manufacturer first, you could save a ton of money.
