The tubing is installed in a heavy-duty fabricated steel head with threaded NPT connections. Packaged boiler is the most common and efficient type of fire tube boiler used in industry to produce steam and hot water. This boiler delivers to site as a whole package factory assembled. The package boiler only requires electricity, water, steam and fuel connections and it is ready to produce steam. A boiler is used in many industries such as in steam power generation, in sugar industries, in textile industries for sizing and bleaching etc. Today we will discuss about Cochran boiler. Cochran boiler is a modified form of fire tube boiler which has various fire tubes which exchange heat to water through convection.
We know that boiler is used onboard for power generation and it is one of the most important thing on ship. Boiler is broadly categorized into water tube boiler and fire tube boiler. And since they are categorized differently this means that there must be some differences between them either in functioning, maintaining, running or economical differences. This article is all about their differences. In fire tube boiler, as the name suggest Fire Tube i. The heat transfer takes place between the hot gases and the surrounded water through the tubes. This heats up the water and convert it into steam.
This is particularly important where boilers operate intermittently or at low load in stop start mode. Easy accessibility of the tubes provides better and lower cost maintenance The outer section of the transfer chamber which is cooled by the water, is equipped with a double compartment. This eliminates the frequent problem of stress affecting the tie rods on conventional wet back boilers. Compactness and flexibility The centred furnace tube and the optimised distribution of the second and third pass convection tubes enables best possible use of site space. Operating modes Equipment options include control and instrumentation for either fully manned, supervised or fully unattended operation.
Nice stuff..!! It was very nicely explained the difference between two boiler methods with the example of apple and orange i. Mostly it depends upon the people for which they mostly prefer. I didn't know that watertube and firetube boilers worked in such opposite ways to get the same result. It sounds like firetube systems are a little more complex in their design, but it's interesting to see the advantages of each system. If I need to rent a boiler with easy maintenance, I'll go with a firetube. But if I need something that is more durable, I'll go with watertube.
models all separate the fire tube boiler in three zones: a flue gas zone, a metal zone and the water/steam zone. All three models focus on the.
Steam boiler has a rated working pressure, running over the rated pressure steam boiler becomes unsafe. If the relief valve and pressure gauge failed to work properly, it may cause the explosion of steam boilers. Condensation boiler condensing apparatus refers to an increase in the vicinity of boiler flue gas, the fuel again absorb heat in combustion temperature flue gas discharged from the flue gas sensible heat and latent heat part together, make full use of. Fast modeling of fire tube boilers request pdf strong technical team and perfect after-sales service to our left a deep impression, the successful completion of the boiler installation and commissioning work at a predetermined period.
The main differences between the fire tube and the water tube boiler are the hot gases flow inside the tube and water surround them in the fire tube boiler whereas, In the water tube, water flows inside the tube and Hot gases surround them. Before moving to further detailed explanation lets have some overview of Fire tube and water tube boiler. Note: At the bottom of every article the PDF link is attached make sure if you want you can easily download. A boiler is a closed vessel in which fluid generally water is heated up to high-pressure steam. The boilers are used in power plants, for the generation of steam.
In the last session, we had discussed Lamont boiler , Benson boiler , Cochran boiler , Babcock and Wilcox boiler in a detailed way whereas, in today's session, we will discuss What is a Boiler? Selection of a boiler, Essentials of Good boiler, Classification of a boiler, Diagram of the boiler, Boiler Mountings, and Boiler Accessories in a detailed way. The working principle of the boiler is very simple.
