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.
Heat recovery steam generator is a high-efficiency steam boiler that uses hot gases from a gas turbine for reciprocating engine to generate steam in a thermodynamic Rankine Cycle. This system is able to generate steam at different pressure levels according to chemical process requirements ( …
considered here due to their low heat recovery capabilities. An exanlination of the following areas will be made in this evaluation: 1. Characteristics of flue gases 2. Methods of incinerator charging 3. Types of heat recovery equipment 4. Heat recovery capabilities 5. Typical installation 6. Cost data and economic justification 7. Conclusions
Waste heat boiler of this industry is a waste heat boiler that matched the hazardous waste and medical waste incineration equipment; it uses exit flue gas heat of refuse incineration equipment to produce steam of nominal parameters.
A heat exchanger is used to absorb the heat from the furnace gases to heat water, which is turned into steam. This steam will go through the Heliex system, where it will be used to generate electricity, before being condensed to water and then returned to the heat exchanger to start the process again.
heat recovery steam systems Selecting the appropriate "heat recovery steam generator" (HRSG) for cogeneration (CHP) and fume incineration systems involves much consideration. Important areas of concern are controlling/bypassing the waste heat, optimizing overall system performance, maintaining required operating pressures, boiler size, weight
Waste Heat Recovery Units. Inciner8 use mainly Waste Heat Recovery Units (WHRU). These are simply heat exchangers that use heat from the hot gas exhaust and transferring it to a water or oil. Larger systems with high volume gas streams, can also use our Steam Rankine Cycle System to …
The function of the combined cycle heat recovery steam generator (HRSG) system is to provide a method to extract sensible heat from the combustion turbine (CT) exhaust gas stream. The heat is converted into usable steam by the heat transfer surfaces within the HRSG.
steam generation The starting point in the engine ering of 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.
Author: Technical Training Professionals 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 ).
Visual inspection, in combination with analytical devices, provides condition assessments needed to ensure that Heat Recovery Steam Generator’s (HRSG) operate safely and efficiently. Annual visual inspections of HRSGs can reveal important details about the condition of components, including insulation damage, external tube damage, through
