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.
File Size: 1MB The boiler tubes are placed between steam distribution drums and water collectors at the bottom of boiler. A super heater is placed before steam distribution system. 188.8.131.52 Heater Fuel. A combination of natural and refinery gas, coal, and fuel oil are applied as heater fuel.
Steam distribution headers are fabricated out of carbon steel or alloy steel seamless tubes. Customized or tailor made items are offered. Headers, after fabrication, are stress relieved to make the Steam distribution headers free from stresses.
distribution system for taking the steam to the areas to be heated. The term distribution system, as used in this chapter, refers to the network of piping required to distribute steam from a boiler room or a boiler plant through the steam pipes to the equipment using it. In this chapter, both exterior and interior steam distribution systems are
Mar 15, 2019· Boiler Blowdowns. Besides a steam distribution system, another heat source for many commercial buildings is a boiler. Boiler blowdowns involve pumping water from a boiler to adjust chemical levels for minimizing scale and corrosion in the system. Blowdowns also clean the boiler by “blowing” out suspended solids circulating in the system.
Steam Boilers & Steam Distribution Systems Course Description This workshop utilizes live experiments and demonstrations to cover all facets of steam system care: boiler auxiliaries, combustion equipment, water treatment, steam traps, plus addition valuable information.
Lack of insulation can decrease the effectiveness of the steam distribution system because of parasitic heat losses. Thermographic inspection of the complete system is the simplest way to quickly reveal heat losses and areas for potential insulation enhancements like boiler rooms, pre-blow areas, main distribution pipes, around blow machines.
This document is for personnel involved in all aspects of medium sized boiler plant, steam distribution and saturated steam used for both general services and direct process purposes in all industries: 1. Process engineers 2. Energy managers 3. Procurement staff 4. Technical managers 5. Operations managers 6.
PG 18-10 – STEAM, HEATING HOT WATER, AND September 1, 2016 OUTSIDE DISTRIBUTION SYSTEMS DESIGN MANUAL . Vol 1 ST EAM BOILERS 2 . 1.3 Boiler System Capacity:
Steam pressure is governed by certain factors as mentioned below: The maximum allowable safe working pressure of a boiler; The right pressure requirement of a plant process; When steam travels through distribution network, the pressure drops due to. Frictional resistance within the pipe which in turn is determined by pipe sizing and velocity.
That leaves two heat distribution systems -- steam radiators and hot water radiators. Steam Radiators Steam heating is one of the oldest heating technologies, but the process of boiling and condensing water is inherently less efficient than more modern systems, plus it typically suffers from significant lag times between the boiler turning on
