Removing the myth of fouling in Concentrated Solar Power

Fouling in steam generators designed based on traditional boiler principles (ASME and EN power boiler standards) however is a mistakenly applied factor for two simple reasons: Firstly, the HTF is not heated but cooled in the steam system. When high temperature HTF enters the steam generator, the heat reacts with water and converts it into steam.

Heat exchanger

A heat exchanger is a device used to transfer heat between two or more fluids.Heat exchangers are used in both cooling and heating processes. The fluids may be separated by a solid wall to prevent mixing or they may be in direct contact. They are widely used in space heating, refrigeration, air conditioning, power stations, chemical plants, petrochemical plants, petroleum refineries, natural ...

Energies | Free Full-Text | Online Ash Fouling Prediction for Boiler

Depending on its operating conditions, traditional soot blowing is activated for a fixed time. However, low-frequency soot blowing can cause heat transfer efficiency to decrease. High-frequency soot blowing not only wastes high-pressure steam, but also abrades surface pipes, reducing the working life of a heat exchange device. Therefore, it is necessary to design an online ash fouling ...

Boiler Components

Venturi register. Matched to a venturi register, a very stable efficient flame is formed. The Fuel/Steam mix exits the nozzle in a series of conic tangents, fuel reversals inside the fuel cone allow efficient mixing with air over a wide 'Turn-Down ratio (20:1).

Online Ash Fouling Prediction for Boiler Heating Surfaces

High-frequency soot blowing not only wastes high-pressure steam, but also abrades surface pipes, reducing the working life of a heat exchange device. Therefore, it is necessary to design an online ash fouling monitoring system to perform soot blowing that is dependent on the status of ash accumulation.

Improve the Performance of Your Boiler System

boiler system by reducing the amount of steam required by the deaerator to heat the boiler feedwater. The differ-ence between these two pieces of equipment is the heat-ing medium: The condensing economizer uses the boiler fluegas to heat the water, whereas a BDHR system uses the boiler’s continuous blowdown water.

BOILER CLEANING SYSTEMS

vere fouling can build up on the convective heating surfaces of waste and biomass boilers. These deposits reduce heat transfer and also favour corrosion resulting in limited plant availability and reduced efficiency. Clyde Bergemann boiler cleaning systems cover …

Modeling of a steam boiler operation using the boiler

The system for monitoring the fouling of steam boiler contributes to the reduction of fuel consumption in the boiler, reduction of water or steam consumption used for blowing out slag and ash respectively, as well as the increase of the durability of the boiler combustion chamber walls and superheaters tubes.

Fault Diagnostics on Steam Boilers and Forecasting System

The slagging/fouling due to the accession of fireside deposits on the steam boilers decreases boiler efficiency and availability which leads to unexpected shut-downs. Since it is inevitably associated with the three major factors namely the fuel characteristics, boiler operating conditions and ash behavior, this serious slagging/fouling may be reduced by varying the above three factors.
