High quality aluminum silicate fiber is used with fire clay insulation, to control the boiler body temperature below 45℃ and reduce heat lost.Sufficient steam storage room and heating area to generate high quality steam and high thermal power.Condenser is added to recycle the waste heat of the exhausted smoke to increase feeding water’s temperature and reduce flue gas emission temperature and increase the thermal efficiency over 98% and save operating cost.

Environmental protection

Big combustion chamber equipped with Low emission combustion burner effectively reduce the NOx to 30mg/m3. Smoke duct and smoke outlet use internal insulation to reduce operating noise.

Combustion chamber uses full membrane water cooling wall structure and pressurized combustion without smoke mixture.

Energy conservation

Good quality alumina silicate fiber and fire clay insulation material are used and the boiler body temperature is controlled below 45℃ and greatly heat loss is reduced. Combustion chamber is designed with narrow distance tube membrane water cooling wall which has good air proof to reduce heat lost and increase boiler thermal efficiency. Internal inspection holes uses high-alumina refractory and manhole cover seal devices, solving superheat problem in this part caused by using refractory bricks.

CNC manufacturing technology

The key processing technologies such as steel plate blanking, circling, drum and tube plate drilling adopt advanced CNC machining to reduce the assembly stress and prolong the service life of the boiler.

Steel tube cutting, thread tube pressing and convection tube processing all adopt advanced CNC technology.

Automatic production line.

Meaning of "superheater" in the English dictiona

The boiler element that superheats the saturated steam to the desired superheat steam temperature by absorbing heat from the flue gas is called the superheater. A reheater is installed in the utility boiler of a reheat cycle to further increase the

A Comprehensive Look at Conductivity Measurement in Stea

high pressure boiler cycles is typically dominated by treatment chemicals such as ammonia, phosphates, amines, etc. at ppm concentrations which should be well above the ppb concentrations of any contaminants. Therefore, specific conductivity, often with corroboration by pH, is generally used to monitor

Pages - Controlling TDS in the Boiler Wat

There comes a point (depending on boiler pressure, size, and steam load) where a substantial part of the steam space in the boiler becomes filled with bubbles and foam is carried over into the steam main.

What are boiler troubles? - Quo

3,Excess pressure boilers.Overpressure of boiler operation, caused by light components deformation, joint damage, serious can cause explosion. 4,The furnace pipe explosion.boiler explosion, there are up significantly, steam ejector, at the same time, water level and steam boiler pressure drop.

Safe management of industrial steam and hot water boile

Foaming and priming in boilers - Lennte

Priming is the carryover of varying amounts of droplets of water in the steam (foam and mist), which lowers the energy efficiency of the steam and leads to the deposit of salt crystals on the super heaters and in the turbines. Priming may be caused by improper construction of boiler, excessive ratings, or sudden fluctuations in steam demand.

Steam Purity Considerations For New Turbines - PAPT

zSilica will partially vaporize at boiler pressures above about 400 psig zIndependent of boiler carryover zAmount in steam dependent on temperature (pressure), silica concentration and pH zNot a superheater issue, but definitely a turbine issue zGenerally not a problem if < 20 ppb in the steam

Johnston Boiler Company Boiler Glossary - Steam & Combusti

of the boiler, but a back flow of steam from a drop in pressure causes the valve to close. • Normal Operating Water Level (NOWL) - Level of the boiler water at normal operation. • Overfiring - Forcing a boiler beyond its designed steam producing capacity.

Pages - Automatic Level Control Systems - Spirax Sar

If steam loads are high, the variable steam flowrate will tend to increase water carryover with the steam, and will tend to make water levels increasingly unstable with the associated danger of low water level lockout, particularly on multi-boiler installations.

Carry Over From Boiler Drum - brighthubengineering.c

The carryover from boiler drum results in deposits in the internal surface of superheater tubes leading to overheating failures. It also results in deposit in turbine blades which reduces the turbine efficiency. Mechanical carry over take place in a boiler mainly due to drum internals; drum level, foaming and spray water.

Pages - Water Levels in Steam Boilers - Spirax Sar

Water Levels in Steam Boilers. The task of any steam boiler is to provide the correct amount of high quality steam: safely, efficiently, and at the correct pressure. Steam is generated by heat from the combustion of fuel in a furnace, or by waste heat from a process.
