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.
The steam pipe sizing can be done on the basis of two methods namely; A. Velocity. B. Pressure Drop. A. Pipe Sizing based on Velocity. Steam pipe sizing calculations are based on the specific volume of steam while using the velocity method. For dry saturated steam lines, the velocities considered range between 25-35 m/s. or 80-120 ft. /sec.
Pipe Sizing Steam Supply and Condensate Return Lines Definitions Steam mains or mains carry steam from the boiler to an area in which multiple steam-using units are installed. Steam branch lines take steam from steam main to steam-heated unit. Trap discharge lines move condensate and flash steam from the trap to a return line.
Author: Anup Kumar Dey Steam pipe sizing is easy with today’s sizing programs. When using a sizing program to select steam pipe sizes, the engineer or contractor is asked to fill in the capacity, the steam pressure, and the velocity required. The answer is a pipe size and a pressure drop per 100 feet of …
Jun 14, 2018· Place the boiler high enough. Make sure to place the boiler high enough to keep the new water level close to the old water level and pay attention to the “A” dimension measurement. Pipe the boiler according to the I&O manual. Use proper pipe sizing from the boiler size chart. The boiler header should slope slightly down.
New England Kiln Drying Association – Steam Design & Best Practices – HerLine Technologies Strainers Strainer Control Valve Note: Turn steam pipe line strainers 90°so the “Y” is parallel with the floor, not pointing down at it. This will eliminate the condensate pocket shown here.
Calculates steam velocity and pressures drop per 100 feet of calculated pipe size Allows quick sizing of condensate return lines Values from "Weight-Flow Rate" and "Velocity of Steam" charts automatically considered – no need to look up information.
The steam-generating facility, located in the boiler room, consists of boilers, feedwater systems, heat exchangers (e.g., economizers), boiler and system controls, fuel and gas handling equipment (e.g., fuel trains, stacks), and steam/water
Dec 05, 2017· Next, compare this to the color brochure for the steam boiler and choose the boiler that meets the required load. An important note on boiler sizing – all the supply piping in the basement should be insulated with a minimum of 1” of pipe insulation. A better choice would be …
Steam distribution systems and sizing condensate return lines . Sizing Steam Pipes . Steam is a compressible gas where pipe line mass flow capacity depends on steam pressure. Sizing Steam Pipes . Steam is a compressible gas where the capacity of a pipe line …
