Characteristics of boiler feedwater - Lennte

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, phosphates etc, in relation to working pressure.

High flue gas temperature, also known as stack temperature, is very important for boiler efficiency. The average boiler stack temperature has to be between 240 degrees and 475 degree maximum. Once you have exceeded the recommended stack temperature the efficiency begins to decline quickly.

boiler efficiency improvement & heat loss explained in .

Boiler Efficiency Improvement & Heat Loss Explained in .

The combustion efficiency of a boiler signifies the burner’s capacity to burn fuel. It has two parameters that determine the burner efficiency: unburnt fuel supplies in the exhaust and excess oxygen levels in the exhaust. As the value of excess air is increased, the amount of unburnt fuel in the exhaust decreases.

Boiler Blowdown types and Boiler Blowdown calculati

There are two types of boiler blowdown intermittent and continuous. Intermittent or Periodic Blowdown. The intermittent blowdown is given by manually operating a valve fitted to discharge pipe at the lowest point of boiler shell to reduce parameters (IDS or conductivity, pH, Silica and Phosphates concentration) within prescribed limits so that steam quality is not likely to be affected.

As with boiler water TDS measurement, conductivity (μS/cm) x 0.7 = TDS in parts per million (at 25°C). Note: the sample of feedwater that is required is from the boiler feedline or from the feedtank and is not a sample of the make-up water supplying the feedtank. The quantity of steam which the boiler generates, usually measured in kg/h.

Supercritical steam generator - Wikiped

A supercritical steam generator is a type of boiler that operates at supercritical pressure, frequently used in the production of electric power.. In contrast to a subcritical boiler in which bubbles can form, a supercritical steam generator operates at pressures above the critical pressure – 22 megapascals (3,200 psi).Therefore, liquid water immediately becomes indistinguishable from steam.
