High-efficiency boilers can be twice the cost of regular boilers, while high-efficiency furnaces cost only 30 to 40 percent more than lower-efficiency systems. There are fewer manufacturers of high-efficiency boiler equipment. Let's look at some of the advantages and disadvantages of high-efficiency hot water heating. Advantages
Working Principle. Hot water produced by a boiler is pumped through pipes and delivered to equipment throughout the building, which can include hot water coils in air handling units, service hot water heating equipment, and terminal units. Steam boilers produce steam that flows through pipes from areas of high pressure to areas of low pressure,
Fire tube boilers, typically have a lower initial cost, are more fuel efficient and easier to operate. Their capacities are up to 25tons/hr and 17.5 kg/ cm2. Different types of fire tube boilers: Cornish boiler. These are the earliest form of high pressure fire tube boiler.
System Boilers Explained A System boiler directly heats your central heating system and produces hot water for a storage cylinder. They work like a Regular (Conventional) boiler in that they need to store hot water, but unlike Regular boilers they take their water supply directly from the mains.
Jun 13, 2013 · However, one advantage that the firetube boiler does offer is that once it is up to operating pressure, it can handle a sudden upward load surge better because of the large steam disengaging area. The drawback to this feature is once you drop pressure on the firetube, it takes longer to catch back up.
Also, higher steam pressure will be possible than with saturated steam, enabling the steam to carry more energy. Although superheating adds more energy to the steam in the form of heat there is no effect on pressure, which is determined by the rate at which steam is drawn from the boiler and the pressure settings of the safety valves.
High-pressure boilers will heat steam above 15 psi and water at pressures that exceed 160 psig. Temperatures in high-pressure boilers will exceed 250 degrees F. Because of the elevated pressure at which these boilers operate, they need to be monitored to ensure safety at all times.
Aug 22, 2018 · Larger heating surface can be achieved by using more numbers of water tubes. Due to convectional flow, movement of water is much faster than that of fire tube boiler, hence rate of heat transfer is high which results into higher efficiency. Very high pressure in order of 140 kg/cm2 can be obtained smoothly.
Steam boilers produce steam that flows through pipes from areas of high pressure to areas of low pressure, unaided by an external energy source such as a pump. Steam utilized for heating can be directly utilized by steam using equipment or can provide heat through a heat exchanger that supplies hot water to the equipment.
High pressure liquid enters the boiler from the feed pump (1) and is heated to the saturation temperature (2). Further addition of energy causes evaporation of the liquid until it is fully converted to saturated steam (3). 3-4 Isentropic Expansion. The vapor is expanded in the turbine, thus producing work which may be converted to electricity.
Pressure range of the boiler is about 0.7 MPa to 2 MPa and efficiency is 65 to 70%. Fuel in these boilers is added into the grate which heats the gases. Hot gases enter the front section of the boiler and leave the boiler from back and then enter the bottom flue and start moving to front section of boiler.
In contrast to its internal construction, which includes a small steam drum and small diameter tubes, the water tube boiler is used to generate steam having high pressure and temperature. These small internal parts produce high volume steam for high capacity applications.
The advantages of a water-tube boiler are a lower unit weight-per-pound of steam generated, less time required to raise steam pressure, a greater flexibility for responding to load changes, and a greater ability to operate at high rates of steam generation.

Dec 25, 2018 · The various advantages of the boiler are It is a drum less boiler and hence the weight of this type of boiler is 20 % less as compared with other types of boiler . It is light in weight.
High pressure shower systems; Boiler feedwater; Desuperheater feed; Vertical multistage pumps are great for areas that don't have much footprint to spare. Its ability to deliver high pressure output with a single pump body and motor combo is also a plus.
Mar 27, 2018 · Answer Wiki. As compared to fire tube Boilers, water tube Boilers are used for high pressure application because The heat transfer area is more in water tube boilers as Water flows in tube and flue gasses are around the tube, results more heat exchange between water and flue gasses . Just like shell and tube system.
Able to build up a reserve of energy Construction is straight forward One furnace tube and burner Disadvantages: Only 27000 kg/h steam output Large diameter cylinders limit pressure Water-tube Boilers Advantages: Small water content Small diameter tubes and steam drum Able to produce superheated steam Customizable design (flexibility) Disadvantages: More complex construction Complex control systems required Conclusion Shell boilers are for smaller scale applications than water-tube boilers
The boiler manhole-lids are mounted from the inside of the boiler so that the boiler pressure will help to keep them tight. Hence the manholes have to be elliptical in shape to make it possible to take the lid out from the boiler. Boiler Questions and Answers
A boiler is a steel pressure vessel in which water under pressure is converted into steam by the application of combustion. In other words, it is simply a heat exchanger which uses radiant heat and hot flue gases, liberated from burning fuel, to generate steam and hot water for heating and processing loads.
