Product thermal capacity : 1-20 t/h Working pressure : 0.7-2 Mpa Available fuel : Nature gas, coke oven gas, biogas, methanol, liquid propane gas, diesel, heavy oil, light oil, crude oil, etc. Available industries : Heat supplying, chemical, food, textile, printing and dyeing, cigarettes and tobacco, fodder, pharmacy, building materials, brewery, rubber, hospital etc. Introduction:
improvement in efficiency of water tube boiler is a boiler shell type 3 passes wetback oil/gas fired boiler. After fuel is being atomized by burner, flame is full of the wave furnace and transfer heat via furnace wall, this is 1st pass; the high temperature smoke is collected in reversal chamber and then enters 2nd pass which is grooved tubes bundle area; after heat convection, air temperature gradually falls and goes to front smoke box and turn to 3rd pass, which is smooth tubes bundle area, and then enters chimney passing back smoke box and exhausted to the atmosphere.
Technical advantages Digitized manufacture
The key part such as material cutting, rolling, drilling are proceeded by advanced CNC machining process to reduce the assemble stress and extend boiler working lifetime.
The front and back smoke chamber plates are cut by CNC plasma cutting machine and looks tidy and beautiful.
Easy operation and maintenance
Fully automatically operating, with automatically adjustment and protection of burning, water level, temperature and steam pressure.
Longer working life
Smoke tube and tube sheet connection is expanded first to eliminate the gap between them, then adopt automatic argon arc welding to relief the stress and expand boilers working life.
Longitudinal and girth joint adopt advanced automatic submerged-arc welding for good welding quality. All longitudinal and girth joint will have 100% radiographic inspection.
Fin tube us ND steel or stainless-steel material which avoid low temperature corrosion.
Inspection procedure point is set up to guarantee the sequence of expanding and welding, avoid cracking of the tube sheet holes.
Less fuel consumption
High quality aluminum silicate fiber is used with fire clay insulation, to control the boiler body temperature below 45℃ to control heat lost.
Sufficient steam storage room and heating area makes boiler to generate high quality steam and high thermal power.
Condenser is added to reuse the waste heat of the exhausted smoke to increase feeding water’s temperature and reduce emission temperature, which can increase the thermal efficiency above 98% and save operating cost.
2019-5-26 · Boiler Efficiency Improvement Program. Text-version - Figure 2 Figure 2. Boiler Efficiency Improvement Program Boiler water is tested daily in small, low-pressure boiler plants and every hour in large, high-pressure plants. To optimize the performance and improve the energy efficiency of a boiler system, consider other factors.
Water-tube boilers are used in a wide range of industries, for example in energy and district heating supply or the paper industry. Over the 30 to 40-year service life of a boiler system, the burners will have to be modernized several times to meet the requirements of current emission standards, especially for
Author: Praveen Marathur2012-11-17 · Investigation of Improvement in Boiler Efficiency through Incorporation of Additional Bank of Tubes in the Economiser for Typically, on a high pressure water tube boiler, the efficiency improvement with an economizer is 2 to 4%, depending on firing rate . On a high pressure fire tube boiler, the improvement is 2 to 3.5%, depending on
: Ankit TanejaImproving Boiler Efficiency. Your boiler probably accounts for the majority, if not all, of your heating fuel bill. If you tend to budget a fixed dollar amount for this fuel bill, you may be interested in knowing that most boiler systems are, at best, 85% efficient with an average efficiency of only 65% to 75%.
2019-5-21 · A high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which heats water in the steam-generating tubes. In smaller boilers, additional generating tubes are separate in the furnace
2014-9-26 · Improve the Performance of Your Boiler System C hemical process industries (CPI) plants continually strive to increase efficiency and reduce expenses. Depending on the facility, the boiler system can account for a large portion of the plant’s utility costs. Improvement efforts, therefore, often
