Reverse Osmosis Systems & Filters - CFB Steam Boilers

Delivers superior steam quality for safe and efficient plant operations. Reduced boiler blowdown. Lowers boiler operating costs and optimises efficiency of boilers and hot water systems. Long-term corrosion control. Protects boilers from corrosion and extends boiler life. Virtually eliminates system downtime.

Self-acting Pressure Controls and Applications | Spirax

The fall in downstream pressure relative to changes in steam flow is therefore small, typically less than three hundredths of a bar (3 kPa; 0.5 psi) from fully open to fully closed. Although any rise in upstream pressure will apply an increased closing force on the main valve, the same rise in pressure will act on the underside of the main diaphragm and will balance the effect.

BOLLFILTER Automatic Type 6.04 Automatic Backflushing

Liquid filtration for low flow volumes The BOLLFILTER automatic Type 6.04 is an automatic backflushing filter which is used to protect low flow plant systems such as nozzles or valves and ensures that the required level of filtration is maintained to avoid rapid blocking and unnecessary wear.

Boiler water treatment - Lenntech

Description of water treatment in boilers: internal and external treatment The treatment and conditioning of boiler feed water must satisfy three main objectives: Continuous heat exchange Corrosion protection Production of high quality steam External treatment is the reduction or removal of impurities from water outside the boiler.

Hydronics - Wikipedia

Hydronics (hydro- meaning "water") is the use of liquid water or gaseous water (steam) or a water solution (usually glycol with water) as heat-transfer medium in heating and cooling systems.The name differentiates such systems from oil and steam systems. [clarification needed] Historically, in large-scale commercial buildings such as high-rise and campus facilities, a hydronic system may

Modeling, Simulation, and Control of Steam Generation

This chapter describes a modeling methodology to provide the main characteristics of a simulation tool to analyze the steady state, transient operation, and control of steam generation processes, such as heat recovery steam generators (HRSG). The methodology includes a modular strategy that considers individual heat exchangers such as: economizers, evaporators, superheaters, drum tanks, and

be damaged from overheating due to the fact that there is no steam to flow through the tubes to protect them until steam is formed in the boiler. Firebox -The firebox walls are of high temperature firebrick to resist and hold inside the 2000° F. or more temperature of the burning fuel.

Gas-fired steam humidifiers

General characteristics CAREL's extensive experience in the humidification sector has led to the development of gaSteam, the range of gas-fired humidifiers, available in 45, 90 and 180 kg/h models. gaSteam runs on natural gas or LPG, and is fitted with a sophisticated built-in electronic controller that can also manage other types of gas by simply setting a number of burner calibration parameters.
