IBM’s DB2 database software, as with other databases, uses keys to speed up finding data in tables. For example, a bank’s customer database might have a customer account number as a key; to retrieve an account record, a clerk needs only the account number. An atomic key is one composed of a single, simple data item that does not break down into meaningful parts.
Steam-heat exchangers transfer heat from one place to another. For instance, radiators are one type of a steam-heat exchanger. Radiators used to be common residential heating systems, although they've largely been replaced by forced-air units. If you have an older home with radiators, you can control the heat that comes from the radiator into the room. Radiators are connected to a central boiler that provides the steam and heat. Have a professional do a basic check on your boiler to ensure it's running correctly.
A fire-tube boiler generally has several small tubes to carry the hot gases from the boiler fire to the water tank, which heats the water. Usually used in commercial and marine applications, fire-tube boilers should only be maintained and operated by those familiar with commercial-grade heating systems. The fire-tube boiler should be descaled on a regular basis to help prevent mineral buildup inside the tank that interferes with efficient heating and water flow.
The Reliable Steam Engine Company is a U.S.-based steam heating company and has manufactured steam boilers since its inception in the 1960s.

Several types of steam vacuum cleaners are available, including upright, canister and hand-held devices. While these carpet-cleaning machines are purportedly effective in removing dirt, experts and consumers report certain disadvantages.
Any appliance that is constantly exposed to water is prone to leaks, and steam boilers are no exception. Care and maintenance can go a long way toward preventing leaks, but the corrosive effect of water can only be held off for so long. Leaks can occur at a number of points inside and on the surface of steam boiler machinery, and you can detect them by looking for the presence of several signs and symptoms.
A steam vaporizer utilizes water and an electrical heating unit to create steam. Steam is beneficial when the air in a room is too dry and causes dry lips, nasal passages and throat. Steam is also useful to loosen congestion in the nose or lungs caused by the common cold or other illness. Follow the instructions in the owner's manual of the steam vaporizer you are using. If the unit isn't cleaned as directed, for example, the outlets can become clogged, and the amount of steam that's emitted will be less than it should be.

With a few power tools, a couple of hours of your time and some additional supplies, it is possible to create your own laser LCD projector from scratch.
While furnaces heat and distribute air throughout the home, steam boilers send steam through pipes that connect to steam radiators. After the steam vaporizes, it returns to the steam boiler for reheating. Because they operate at higher temperatures than water boilers and consume significant amounts of water to generate steam, steam boilers are less energy-efficient and require more maintenance. Moreover, water feeders must be monitored constantly to ensure a steady supply of make-up water to the steam boilers.
The Intel Atom is a computer central processing unit intended for applications where low cost and power consumption are primary concerns. The Intel Atom is used primarily in small notebook computers called "netbooks" and small form factor desktop computers called "nettops." Intel introduced the Atom in 2008.
Boiler pipes can produce a range of unpleasant noises from gurgling sounds caused by trapped air in the central heating system to humming noises caused by inefficient pumps. Another common annoyance is a knocking or hammering sound coming from the boiler pipes when hot water passes through them. Knocking noises are usually not indicative of major boiler problems and can usually be remedied without professional help.
Insulated boxes are used for thermal transportations of food or other items that need to be kept at a particular cold temperature. The boxes are designed in a way that causes the heat to transfer out of the box, thereby not spoiling the delicate thermal parameters of the items inside. Understanding the properties of an insulated box that help the heat to transfer can aid you in the decision-making process for selecting the most appropriate insulated container.
If you’ve ever walked across an improperly installed floor, you know how irritating they can be. Whether the floor isn’t level or gives when you walk across it, it’s often because support joists aren’t placed flush with one another. Because of this, builders must ensure that they lay joists flush, a job that relies upon precise placement of the hardware that affixes joists to beams, known as joist hangers. While contractors often use a specialized tool, a joist hanger nailer, that sets joist hangers perfectly, a more cost-effective approach is available for homeowners who don’t want to incur the cost…
Headend devices comprise the computer, operating systems and hardware that manage a facility. Though there are almost innumerable systems and programs that control heat transfers, there are several steps administrators can take to attempt managing their devices correctly. Proper maintenance of heat-transfer hardware should be a requirement of the facility schedule, and if any irregular or poor transfers are noted, administrators should first clean transfer coil tubes and replace degraded equipment.
Many production facilities use a combination of coal fuel and steam turbines to power electrical generators. The generator supplies energy to the manufacturing facility for operating conveyor belts and heavy production machinery. However, steam turbines require retrofits, or overhauls, periodically for the best power output to the generator.
Although burning coal is not normally considered environmentally-friendly, newer coal-burning boilers are designed to reduce emissions of harmful gas and particulates. In many countries, 700 megawatt (MW) steam boilers provide energy to homes and businesses. Specifications vary, but these boilers burn fuel efficiently and have low nitrous oxide emissions.
Rigid foam panels add insulation value when installed over the home’s boxing, which is the wood-sheet covering on the outside of the stud walls. Styrofoam is the brand name for rigid foam products manufactured by the Dow Chemical Corporation, and Styrofoam panels are readily available in a variety of thicknesses from local lumberyards and do-it-yourself type centers. Vinyl siding installation methods will alter slightly when installing the siding over rigid foam panels.
Steam heating uses a boiler system in which water is heated through gas- or oil-fired burners and is converted into steam. The steam moves through pipes to radiators that emit heat to warm a room. The steam then cools and returns to the boiler through condensation. This type of system is simple to maintain, doesn't require a large of number moving parts and provides heat that is allergen-free.

Traditional clothes dryers use heated air to remove moisture from damp laundry. New technology allows you to use steam to dry and sanitize clothes. Steam clothes dryers are time-saving and money-saving appliances.
Chances are, the heat in your home is produced by one of two pieces of equipment: a furnace or a boiler. Furnaces produce heat by circulating hot air, while boilers use hot water or steam. If you are having trouble with your steam boiler, or if you are planning to get a new one, it's a good idea to know a little bit about them before you make a move.
Heat transfer is the process of heat moving from a high-temperature object to a low-temperature object. Heat transfer is an important part of most scientific disciplines and engineering, since various natural and manmade processes generate heat, which transfers from hotter to colder locations. Heat transfer can affect various engineering applications. For example, if an engineer designs a device with a part that holds a high temperature, the engineer must also consider that surrounding parts might be affected by the heat, as heat transfers to these nearby objects. Complex mathematical equations help experts predict how heat transfer occurs.
It is easy to be confused by the many different three-letter abbreviations and acronyms used to describe the features and components of consumer electronics. These terms often hide the complexity of the technology and make it easier for marketers to use hype or even falsehood to give their products a competitive advantage. For instance, TFT and LED are two terms describing electronic components used in television, computer and mobile device displays that are not competitive, but complimentary technologies.
If you rely on a steam boiler for heat, the last thing you want is to wake up and find no heat coming out of your vents. Boilers can malfunction in a variety of ways, and an overloaded blower is a common problem. In most cases, it is also a reasonably easy problem to fix.
Weil-McLain oil-fired steam boiler is a tankless unit that has cast-iron sections. The steam boiler has a large water content and a quick-open top. Adjusting the steam boiler should be performed only when the oil or pressure levels move out of recommended ranges or the boiler is not operating correctly.

Today, we are accustomed to new technologies making their appearance on the scene. These new devices are quickly put to use to make life easier and more efficient for ordinary people. Thermal conductivity is a term known to few people, but the technology using its principles is already in play in many fields. One of the most practical applications of this technology is its use in gas leak detection, which can find dangerous, hidden leaks in home heating systems.
One of the most pressing health problems for an aging population is that of osteoporosis, or the gradual reduction of bone density. Osteoporosis can reduce the individual’s activity and increase the risk of fractures, either from a fall or even from just walking. It is important for older patients to determine the degree of bone loss -- if any -- they have so that they can take steps to address it. Ultrasound is often used for this purpose. Ultrasonic waves pass through the body part being tested, and the resulting attenuation reveals the bone density. One of the companies that…
