For many years, manufacturers in the industry have released many HVAC system related products. Boilers, in particular, have been used by shipping companies to power their engines and optimize their courier services. Boilers will for sure still be part of the industry as it has served as one of the backbones of such processes. Some boilers, even the old models, and units are still used until today.
These advancements are due to the fact that there are many equipment and appliances that are powered by either heating or cooling. Using equipment like heating and cooling systems, HVAC technologies or boilers, these apparatuses and machineries are brought to life. A boiler, also known as the steam generator is a device that applies heat energy to water in order for it to produce steam.
Fluid, mainly water, is heated inside a boiler and it does not necessarily need to boil. The steam or vaporized fluid exits the boiler and will then be used in various processes and activities such as cooking, sanitation, water heating, and many more. This makes boilers a very useful tool in navigation, powering warships and boat engines, pasteurizing milk and a lot more, mainly industrial processes in factories, big and small alike.
IHI has been providing highly efficient and reliable coal-fired boilers which cumulate the state-of-the-art technologies to the world. Through coal-fired boilers completed on the basis of IHI’s clean coal technologies formulated by way of long term experiences and researches, we contribute to more effective and economical utilization of relatively low price coals. In the same time, we are supplying the domestic and overseas customers with boilers applicable to a variety of fuels as well as coal, and researches and development are underway to bring into markets oxy-fuel technologies to reduce carbon dioxide emission and a new gasification system and pre-dried technology to make possible good usage of lower rank coal like lignite, in addition to flue gas treatment facilities. We aim at early launch of those technologies.

A furnace, on the other hand, is a device used for high-temperature heating. Furnaces may be fueled by heat energy coming from fuel combustions, electricity, or through induction heating. Basing on their efficiency and design, furnaces can be classified into four general categories.
The first category of furnaces is called a natural draft. The first category of furnaces actually consists of cast-iron or riveted-steel heat exchangers. The second category is called forced-air and had an atmospheric burner style with a cast-iron or sectional steel heat exchanger. Forced draft is the term for the third category of furnaces. It is a mid-efficiency furnace with a steel heat exchanger and multi-speed blower. The high-efficiency or condensing furnace is considered as the fourth category of the furnace. High-efficiency furnaces can achieve from 89% to 98% fuel efficiency.
This category can be interpreted a couple of different ways. But, for our purposes, we’re going to say that electric furnaces are air handlers. You can pair an air handler with your air conditioner or heat pump. It contains your air distribution system, indoor coil and sometimes heat strips that provide additional heating power. These heat strips are powered by electricity and create original heat.
- Don’t have to use natural gas
- Can be all you need to heat/cool your home year round (in some areas)
- Create original heat (don’t transfer heat)
- Can raise electric bills
- May have to strain to reach heating demand (in some areas), particularly if you are pairing an air handler with an air conditioner

The steam boilers give off can have different uses such as sterilization, running of production equipment, but most importantly it is commonly used to give off warmth into the interior of the home, office and many more. This makes boilers a very useful tool in navigation, powering warships and boat engines, pasteurizing milk and a lot more, mainly industrial processes in factories, big and small alike.
However, due to old age, some boilers already fail to function and were considered as obsolete or outdated, thus they cannot be used anymore. There are some boilers, however, that was repaired and restored for them to be used again today. As they are already configured to cope with modern technology, they can now be utilized again by the industry.
