Q:What is the meaning of the equipment level A, B, C, and D shown in the equipment case when the boiler is informed online?
Class D: Steam boiler with rated steam pressure less than or equal to 0.1MPa; hot water boiler with rated water temperature less than 120 ℃ and rated heat capacity less than or equal to 2.8MW
Q:is it true in a hot water system the thermostat controls the hot water valve and the boiler?
It's control the gas it tells the gas valve shut of the flame when the water heat up to certain temperature
Q:I don't have an actual double boiler, so is it OK to boil water in a regular pan and put a metal bowl on top of it? I'm melting chocolate to dip some candy in. Can I melt all the chocolate and keep it on the heat without it scorching or is it better to do it in batches? Bear with me, I'm a terrible cook! Thank you!
User a large pan top boil the water. Once it is boiling. Remove from stove and place the small pan in the larger pan with water and stir the chocolates until milted. Then, start your dipping process. If the chocolate gets stiff add some of the hot water to the mixture and stir.
Q:How to improve efficiency of Boiler?
There are various aspects of boiler efficiency e.g 1.Thermal efficiency improves by reduction of heat losses in radiation/ flue gas and ash , improved combustion efficency by better fuel, air/fuel ratio to limit excess air , operation at design load , waste heat utilisation by economiser/ aitheaters, optimised regenerative feed heating , Vaiable speed /frequency drive for large fans e.g I.D/ F.D /PA/ BFD pumps , condensate recovery and blowdown minimisation . 2. operational efficiency by better reliability / availability , quick start up/ load throw capability by automation, plant capacity utilisation and high plant load factor, solid / gaseous effluent norm adherance capability , safety aspect and accident prevention . 3 . maintenace efficiency : by minimisation of corrosion and tube failures by proper corrosion control and preservation . preventive and periodic maitenance practices. You can see that it is not only one aspect but a group that require to be taken care of to improve efficiency of boiler by a group . Each group need attension and improvement for overall improvement. Only joint effort of the O and M group / design group can fetch fruitful results .
Q:just want to know,TQwhen a steam boiler system for a plant having thermal deaerator, do we still need a flash vessel to separate the flash steam and return condensate?and if let say we install an economizer, the feedwater after the economizer will be pumped into boiler water tube by the feedwater pump, even though its temperature is around 150'C, it will not become steam because of the pressure, but when it reaches the water tube of the steam boiler, will it become steam?because the water tube have one sensor where it will detect the water level inside the tube,if steam formed and water level low, the boiler will have problems?help help helpTQ
Most steam systems pump the condensate to the deaerator where any non condensables such as air are removed. The condensate is then pumped by the boiler feed pumps to the boiler either through an economizer depending on the system design. The amount of boiler feedwater that is pumped to the boiler will depend on the water level in the boiler. As the steam demand varies more or less water will be added to maintain the correct level. The fire from the burner(s) will also vary to maintain the pressure in the boiler. It is the burner flame that produces the heat that vaporizes the water into steam. Most boilers have a steam drum at the top of the boiler that all of the tubes connect to. It here that the water level is maintained. In the case of fire tube boilers the level is a bit different but still controlled in a similar matter. See the two links below for infor on water tube and fire tube boilers. On very large industrial and power boilers the control of the boiler feedwater and the boiler level is maintained by an elaborate system of level sensors and flow sensors so that the boiler level can be maintained more accurately than with just a simple level control. The flow sensors can detect a change if steam load and begin to adjust the water level before there is an actual change in the level.
Q:The plumber said there are two types of boiler/radiator heaters. One is a cast iron and I believe he said the other was a thin fin. Which is better? The burn natural gas. Mine has gone out
What is a Furnace? A furnace is an enclosed heating unit that heats air by transferring heat in a metal combustion chamber to the air and circulating it throughout heating ducts in the house. Furnaces can run on electricity, natural gas, propane or fuel oil. What is a Boiler? A boiler is a heating system that consists of a sealed chamber that converts water to steam or heats water for circulation in a hydronic heating system. If you have radiators distributed throughout your home you have a boiler. (Although some boilers distribute heat through baseboard heaters or even radiant pipes embedded in your floors!) What Is a Heat Pump? A heat pump is an electric air conditioning and heating system that captures existing outdoor heat and transfers the heat into the home. Like a warm-air furnace a heat pump distributes heat through the air ducts in your home. Your Current Heating System: What You Need to Know Before purchasing a new heating system, you need to know what type of heating system you currently have. (If you have a boiler and your want to install a warm-air furnace you would need to go through the expensive process of installing new ductwork!) Three things to consider when purchasing a new or upgrading your heating system:
Q:can i use spray paint near my gas boiler if i turn it off first?
DO NOT USE ANY THING NEAR YOUR GAS BOILER THAT HAS ANY KIND OF FUMES. My husband was inflating a wheelbarrow tire in the basement, and was close to our gas furnace, which has a pilot light. The furnace was not running, but when the fumes from the can of tire inflator reached the pilot light, it ignited and he was encircled in flames for a second till the fumes were burned off. Luckily, he was not burned, but the wheelbarrow tire continued to burn and he had to carry it outside while it was burning. If you use a can of spray paint and that happens it may explode in your hand, or you could be burned by the fumes igniting like what happened to my husband. Another thing that could happen is a build up of fumes if the boiler is in an enclosed area and that could ignite and cause an explosion. (Sorry for the capital letters, but I wanted you to notice what I said). (Please be careful, fumes are very dangerous).
Q:Our central heating Boiler was getting its annual service, the Engineer told me that my boiler is no longer being produced and it might be hard to get replacement parts in a few years time (my boiler is vokera linea and is about 12 years old)He said that our boiler was a combi boiler and most new boilers were condenser boilers nowadays – what exactly is a condenser boiler and how is it different from a combi boiler ???
You were given false information and he is probably doing it to persuade you to order a new boiler from him. My daughter has just had a new combi boiler installed and it is also a condenser. It doesn't matter whether it's a straight boiler or a combi, it can still have the right technology installed to make it a condenser. As this guy has given you false information you should get rid and find another guy who is more honest. My next move would be to take into account that most boilers have a life of around 15 years and start to put some money aside for when you may need a new boiler in around four years time.
Q:peerless boiler how to keep water level?
On a steam boiler you can in stall an automatic fill valve works like ballcock in your toilet or check the sight glass every few days Ahot water boiler is filled by itself from street pressure
Q:I have a 120k BTU Weil Mclain Gold hydronic boiler, with tankless domestic coil installed, about 84 AFUE - I think a model SGO something, guessing it's between 8 and 12 years old, one of the pale yellow units. It works but we're converting to gas. Is there a market for a used oil boiler in Central NJ, and how much would you guess it could sell for?Thanks.
The thing is, most people who need a boiler hire someone to install it because it is a pretty hard-core job for the average do-it-your-selfer. Since they are putting a lot of money into the job for labor, they usually get a brand new unit (rather than risk getting a used one that could fail at any time and probably not have any warrantee). Also, a lot of the tradesmen don't like to put in used equipment as, it is hard to predict how much life it has left, fittings 'n things are often rusted solid makes the job take longer and, if something busts/goes wrong, it never ends well. The person who would be interested in it would probably be someone who would do the work themselves, and, if they are doing it themselves, it is probably because they don't have a lot of money. If it was a hot air furnace, somebody might buy it for a workshop/camp (because they don't have to worry about heating pipes freezing when not in use). Where I live, you would be lucky if you can get somebody to take it for free for the scrap value.
