WNS series horizontal internal combustion 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.
1. 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.
2.Easy operation and maintenance
Fully automatically operating, with automatically adjustment and protection of burning, water level, temperature and steam pressure.
3. 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.
4. 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.
Introduction to Commercial Building HVAC Systems and Energy Code Requirements Reid Hart, PE, Pacific Northwest National Laboratory Heating: a boiler generates hot water or steam that is piped to heating coils fan and reheat energy use will be higher because the turndown of
Aug 09, 2000· Reheat can be used just as it is for conventional systems, using vav boxes with coils. Thus, dual-duct systems are not necessary, nor a mixing plenum as the case may be. This saves a lot of ceiling space, and floor space as well, because the footprint of the heat pump system is smaller - all of which contribute to lower cost.
The superheater temperature control can be done by many ways. Methods like desuperheating by water injection, flue gas flow diverting, burner tilting are few of the commonly adopted systems. In large capacity boilers the injection type desuperheating is adopted for superheater temperature control. Reheater in power boilers can also be technically classified as superheaters, however the type of
Jan 08, 2018· What is Reheater on Boiler? – Reheater is a part of boiler which to reheat steam output from the first level of steam turbine. Reheated steam will again absorb the heat energy from boiler to be used in the next level steam turbine. Reheater is one way to …
Rheem Manufacturing ranks as the global leader in the manufacture of high-quality, sustainable, and innovative water heaters, tankless water heaters, air conditioners, furnaces, pool heaters, and HVAC systems for residential and commercial applications, and is a full member of AHRI, the Air-Conditioning, Heating, & Refrigeration Institute.
In this manner, a WSHP system provides a form of heat recovery and an opportunity to save energy by reducing the need to operate the boiler or cooling tower. For example, if the water temperature stays in the desired range—between 60ºF (16ºC) and 90ºF (32ºC)—neither the …
Oct 26, 2017· For residential and commercial/industrial purposes, there are 2 types of boilers. The most common is the fire tube design. This would include the common sectional type boiler seen in most residential applications. The fuel is burned, and the hot gases pass through a series of flue passages or tubes that are generally steel.
System Boilers from Vaillant. Choose the right system boiler for your home. System boilers, also known as sealed system boilers, are the perfect solution for larger family homes where you might have many people using multiple sources of hot water at the same time.
The reverse-return piping system is more costly, due to the additional length of return piping required, but is often justified where flow control is critical. For hydronic systems that provide both heating and cooling, the distribution system may be configured as either a 2-pipe system or a 4-pipe system. A 2-pipe system is shown in Figure 3.
The above are the major water and steam circuit items in a boiler and are collectively called the ‘pressure parts’. This post is part of the series: Working Of A Power Plant Boiler. Boiler in a power plant has two functions. The Combustion system converts energy in coal to Heat.
Sep 21, 2005· A new school that was put into use this fall has a very strange problems. In the month of July they had a nat. gas bill for $17,000 dollars. All of the gas was used for heating water for reheat into the rooms thru VAV boxes. The Best I can tell from talking to the control co. , engineer and the general contractors engineer the cooling unit delivers a constant 55 deg. air all the time, if the
