Introduction of WNS gas / oil fired steam boiler:

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.

Technical advantages:

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.

Several methods are possible to limit oxygen ingress to storage tanks and steam generators, and Terry Bundy personnel selected a gas transfer membrane technology to remove oxygen from makeup water.

Design methodology of heat recovery steam generator

Sep 12, 2018· The first step in designing a HRSG is to calculate the steam generation ability, and gas and steam temperature profiles. The flow rate and exit steam temperatures can be assumed based on the specifications for a conventional fired steam generator. The choice of these two factors then affects the sizes of the superheater, evaporator and economizer.

Of the three main components of the CCPP—gas turbine (GT), heat recovery steam generator (HRSG) and steam turbine (ST)—the GT has gone through numerous innovations and improvements.

Heat-Recovery Steam Generators: Understand the Basi

a HRSG is the evaluation of its steam generation capability and gas and steam temperature profiles. For a conventional fired steam generator, one can assume a desired steam flow rate and exit gas temperature and then fire the necessary amount of fuel to meet the steam demand. A HRSG be haves differently due to the low inlet gas

HRSG FORUM REPORT - Turbomachinery Magazi

Nov 03, 2019· This significantly decouples the GT output from HRSG and ST constraints. The goal is to provide more MW in less time, lower the fuel burn, reduce load imbalance and start emissions, and lower startup costs. However, it causes a redistribution of heat through the HRSG’s gas path. A detailed HRSG and ST assessment was done by Uniper.

Difference Between Heat Recovery Steam Generators (HR

The steam turbine or a downstream process uses the steam. The term HRSG refers to the waste heat boiler in a Combined Cycle Power Plant. In its basic form these are bundles of water or steam carrying tubes paced in the hot gas flow path. These recover the heat from the gas to generate superheated steam, hence the name Heat Recovery Steam Generator.
