The furnaces can be divided into four categories -.house hold, industrial, metallurgical, and incinerating. The household furnaces are designed to be installed inside or outside the homes and are mainly used to heat water and keep the homes warm in winter times. Usually, fuels like natural gas, coals, water, and wood are used to run the domestic furnaces.
Gas Furnaces: These days, gas furnaces are the most preferred form of household. These are fueled by natural gas, which can be purchased from a local company. The natural gas is more efficient and more clean burning than most of the other domestic fuels. Generally, gases like liquefied petroleum gas (LPG), biogas, and methane gas are used to fire a gas furnace.
The gases are equipped with an igniter and a thermostat, which senses the room temperature. When the thermostat records a temperature below the programmed temperature, the igniter will turn on and then the furnace will start to burn the gas. Industrial Engineering Book The resultant air will be distributed throughout the house by a duct system. In some gas furnaces, especially in the old ones, the gas is lighted by a pilot light. Most of the newer gas furnaces use an electric spark to ignite the gas.
Oil Furnaces: Many homeowners prefer to use oil furnaces for heating their homes. Oil is the most easily available natural resource whereas the other forms of furnace fuels are not so abundant. However, the oil furnaces are not as efficient as gas furnaces and require more electricity than the gas.
Most oil furnaces have a storage tank from which the oil can be piped into the combustion chamber of the furnace, where it will be atomized. In the oil furnaces, Industrial Development Painting high-voltage electrodes are used to ignite the atomized fuel. The heat is then circulated throughout the house by a forced-air circulating fan.
Wood Furnaces: The wood furnaces use wood pellets or logs to generate heat. Both indoor and outdoor wood furnaces are available in the market. They use either hot water or forced air flow to produce and circulate the heat. Generally, the wood is cheaper than the other furnace fuels and naturally wood furnaces are cost effective than most of the other domestic furnaces. A wood furnace consists of many parts, including a cabinet, sealed firepot, blower, draft fan, thermostat, and a chimney.
All household furnaces, particularly the gas, oil, and wood furnaces, require to be periodically cleaned in order to maintain an efficient heating system. If not maintained properly, these furnaces may emit hazardous fumes. Hence, they should be regularly checked by an experienced professional, at least once in a year. The furnaces that have higher AFUE ratings are more efficient and require much less fuel..
Electric furnaces are also available in the market. The main advantages of electric furnaces are that they are safer than other domestic furnaces and do not produce carbon monoxide or any other hazardous fumes. However, these furnaces are very expensive and it …

Chrome Plating in Automotive and Household Industries
In recent decades, chrome plating has become one of the most popular metallic finishes available, and it is widely used in several industries.
The automotive industry is the single largest consumer of chrome plating, which appears on trim and accessories for many cars and motorcycles.
Other industries have been picking up on this trend, and chrome plating is now utilized for household fixtures and fittings as well, and even fishing lures. In recent years, chrome plating is available in satin finishes also. Satin chrome is a good aesthetic match for stainless steel and aluminum finishes.
Chrome is both attractive and durable, and as such, it has become a staple finish in the automotive industry. At one time, steel was used for car bumpers and body parts; however, it was later discovered that plastic was lighter, cheaper, and easier to manufacture.
The only problem with plastic components was that they were not as shiny and attractive as metal parts. During the 1970s, this problem was solved with the advent of a technique for electroplating plastic components with metallic finishes, thereby offering all of the advantages of plastic parts, as well as the beauty of metal. Chrome trim was always more popular in North America than in other parts of the world, and reached its peak usage there during the late 1980s and early 1990s.
It has steadily increased in popularity in other areas of the world as well; its popularity has risen by 50% in Europe, since 1993, and has almost doubled in the United Kingdom during the same period. Chrome plating’s resistance to oxidation and corrosion, its ability to withstand environmental extremes, its ease of care, and its ultra-bright specular finish make it an ideal plating material for automotive trim and accessories.
Components can come from the factory already chrome-plated, or they can be plated by the consumer after vehicle purchase. There are many companies which specialize in electroplating, and many automotive finishers which specialize in just chrome plating. Business Tendency Index Indonesia Aside from its other advantages, chrome plating is also advantageous because it saves consumers time and money in searching for and purchasing new parts for their vehicle, as damaged or worn parts can simply be re-plated instead of being replaced.
This process is more cost-effective than purchasing a new part, and also reduces waste and, therefore, environmental impact.
Household fixtures are often plated with chrome, because they require many of the same qualities of vehicle Secondary Industry Def trim. Bathroom fittings, doorknobs, handles and many other household items are often plated with chrome.
Before chrome, these items were sometimes plated with silver, copper or brass but they were difficult to maintain. Silver plating tarnishes, copper plating corrodes, brass plating is prone to verdi gris corrosion;chrome plating is as aesthetically pleasing as other metals, if not more so, and doesn’t have any of the disadvantages of these other metals.
The versatility, beauty, durability and easy cleaning of chrome plating have made it one of the most popular metallic …
