Plant Engineering | Maintaining boiler safety

Basically, there are two types of boilers. These are the fire-tube and water tube boilers. In water tube units, water is circulated within the tube and heated by hot gases from the furnace until it becomes high-pressure steam. On the other hand, fire-tube boilers have water surrounding them. Hot gas is passed through and this heats up the water.

How to Destroy a Boiler -- Part 1

Jul 01, 2014 · Such leaks, which transfer raw cooling water directly to the condensate, introduce many impurities, including such deleterious compounds as chlorides, sulfates, hardness, and silica. In one case in the early 1980s, operation of an 80 MW, 1,250 psig utility-boiler for three weeks with a condenser leak resulted in severe boiler-tube hydrogen damage.

Failure investigation on rear water wall tube of boiler

This action could potentially result in water wall tube overheat damage due to the interruption of the boiler's natural circulation. The lower water wall headers should be routinely blown down every time the unit is brought out of service after fuel firing has been halted and the unit is still under pressure.

Apr 23, 2018 · Advantage and Disadvantage of Water Tube Boiler. Steam is an important source of energy for our modern age. We are using steam from the very beginning of our first industrial revolution in human history. Now we are using steam from the Textile Industry to Power Plant. In a Nuclear Power Plant steam use on a huge scale. For common usages, we use….

Feb 24, 2012 · 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/cm 2 can be obtained smoothly. Working Principle of Water Tube Boiler

Water Tube Boiler Parts And Their Functions--ZBG

High boiler water alkalinity increases the potential for foaming, particularly in the presence of suspended matter. Where a chemical species is sufficiently volatile, it also carries over as a vapor in the steam. Total carryover is the sum of the mechanical and vaporous carryover.

Aug 19, 2019 · In the same way, a fuel source is burned in the furnace, causing the water tubes inside to heat up. Once again, when the water is boiled, steam is generated and moved downstream. A water-tube boiler is more thermally efficient than a fire-tube boiler, but they are more complex to construct and the quality of the water can be a limiting factor.

Boiler Water Tube Industrial

Fire Tube Boiler Versus Water Tube Boiler . At their core, boilers are really just large heat exchangers that take the energy from combustion and pass it into the water on the other side of the internal components (tubes, drums, furnace, etc.). One of the first questions that come about when looking into boilers …

Advances in Boiler Cleaning Technology | Power Engineering

Boilers rely on the water to protect the steel boiler tubes from the temperatures in the furnace which greatly exceed the melting point of the tube material. A buildup of deposits inside the tubes will produce an insulating layer which inhibits the ability of the water to remove the heat from the tube.

Sulfite Testing - The importance of properly cooling your

Waterside tube corrosion is generally caused by the existence of contaminants in the boiler feedwater, which is a combination of makeup water and condensate returns. Feedwater contaminants include oxygen, excessive water treatment chemicals, oils, miscellaneous metals and …

Difference Between Water Tube Boiler And Fire Tube Boiler

Water-tube boilers are used in power station applications that require: A high steam output (up to 500 kg/s). High pressure steam (up to 160 bar). Superheated steam (up to 550°C).

Another problem associated with water chemistry and water-side deposits is the corro- sion of the tube. A common corrosion problem is the pitting of tubes due to the ingress of oxygen into the boiler water. The oxygen tends to attack welds and backing rings preferen- tially and can lead to eventual failure. In addition there are two major types

The water tube boilers are mainly used for generating steam with high temperature as well as pressure. The internal structure of this boiler includes a tiny steam drum, small width tubes. The components of this boiler generate high-volume vapor for high-capacity applications.

All You Need To Know About Boiler Tube Cleaning | Techcolite

Oct 01, 2009 · 1.. IntroductionFailures in boiler tubes have been discussed and summarized in Refs., .As reported in Ref., erosion is listed in top ten failure causes, and based on samples submitted to Davis N. French Inc., it gives 6.5% of the all the failure causes.According to the failures by location, water wall tubes are the second highest failure location after superheater tubes.

What is a Boiler and How Does it Work? | RealPars

Feed-water purity requirements therefore can vary widely. A low-pressure fire-tube boiler can usually tolerate high feed-water hardness with proper treatment while virtually all impurities must be removed from water used in some modern, high-pressure boilers. Only relatively wide ranges can be given as to maximum levels of alkalis, salt, silica
