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.
when conventional plate heat exchangers (PHEs) are used as steam heaters. The first is that when water is heated over a relatively wide temperature difference, e.g. from 10 to 70°C (50 to 158°F), the high steam velocity causes erosion and noise problems. The second is that when high water flow rates are used when heating water only a few
3.3.1 Heat recovery steam generation. The HRSG recovers heat from the gas turbine exhaust to generate steam at temperatures up to ~650°C and pressures of 13–20 MPa. Although SC systems have been developed, heat-recovery steam generation is most commonly applied under subcritical conditions.
The growth of the global heat recovery steam generators market is likely to gain from the regions of Middle East & Africa, Asia Pacific excluding Japan, and Eastern Europe, owing to increased instalments of greenfield projects of new co-generation and combined heat & power plants by public and private enterprises with a projected growth above
a waste heat recovery system compris-ing both steam and power turbines, and combined with utilising scavenge air energy for exhaust boiler feed-water heating. This paper describes the technology behind waste heat recovery and the potential for ship-owners to lower fuel costs, cut emissions, and the effect on the EEDI of the ship. Introduction
This section is intended to provide turbine operators with a basic understanding of heat recovery steam generator (HRSG) design and operation. The power generation block of the facility produces electrical power in two separate islands: The first island within the combined-cycle power block is the combustion turbine (CT) generator set.

Author: Technical Training Professionals Since the heat produced during the generation process is fed to a further use: for example in conventional heat-recovery boilers downstream of gas turbines or in heat-recovery boilers equipped with auxiliary firing, fresh-air operation as well as smooth change-over and can hence respond flexibly to the most widely differing operating conditions.

Anguil Environmental installed an Air to Steam, Waste Heat Recovery Boiler to recover exhaust waste heat from the natural gas fired thermal oxidizer and produce 25 psig of steam. The boilers use X-ID tubing for enhanced heat transfer through the helical ribs on the inside of the tubes.
· Dec 19, 2015A heat recovery steam generator or HRSG is an energy recovery heat exchanger that recovers heat from a hot gas stream. It produces steam that can be used in a process or used to drive a steam turbine.
A heat recovery steam generator (HRSG) is an energy recovery heat exchanger that recovers heat from a hot gas stream, such as a combustion turbine or other waste gas stream. It produces steam that can be used in a process (cogeneration) or used to drive a steam turbine (combined cycle
