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.
Burning coal involves fuel preparation, providing the necessary combustion air and removal of the flue gases and ash. What are the main elements of the Combustion system in a large power plant boiler? Read this article to find the answers. Coal System for power plant. Coal received from the mines is stored in the coal yard adjacent to the power
Cited by: 9 Coal-Fired Power Plant Designs, Systems, and Components Conventional coal EGUs have various designs and configurations but have similar processes. First, units receive, process, and combust coal to produce steam. This steam drives a turbine generator to produce electricity that is fed into the electricity transmission system. Cooling
15 - 60% for coal; Carbon dioxide - CO 2 - is a combustion product and the content of CO 2 in a flue gas is an important indication of the combustion efficiency. Optimal content of carbon dioxide - CO 2 - after combustion is approximately 10% for natural gas and approximately 13% for lighter oils.
Mar 21, 2014· Combustion is needed to power the boilers. The combustion system of the boiler and how efficiently it works, is at the core of operating an efficient boiler. Many significant advances in boiler technology are a direct result of optimizing the combustion …
Figure 3 shows local COe and O 2 sensor response to combustion conditions in the furnace with an intermittent 30-minute air-purging system to clean the sensors on a utility coal-fired power plant.
This paper presents methodology and results of a research project on software optimization of combustion process efficiency in coal-fired power plant. The general goal of this project was to increase boiler efficiency by proper control of the combustion process using optimization software, integrated with Distributed Control System and in
In addition, their Cape Fear plant is the first in the world to install a Swedish combustion control technology, ROFA, on a coal-fired boiler. They are also the first in the U.S. to test a Russian
Apr 09, 2018· The coal power plant diagram shows the components of the plant and the different stages of transforming the chemical energy (coal) into electrical energy as: We started with the boiler or the steam generation system; as we supply the coal from coal bunkers via coal conveyors to …
The energy efficiency of a conventional thermal power station is defined as saleable energy produced as a percent of the heating value of the fuel consumed. A simple cycle gas turbine achieves energy conversion efficiencies from 20 to 35%. Typical coal-based power plants operating at steam pressures of 170 bar and 570 °C run at efficiency of 35 to 38 %, with state-of-the-art fossil fuel
Jan 15, 2019· In pulverized coal fired boiler,The coal is pulverized to a fine powder, so that less than 2 % is +300 micro meter and 70 – 75 % is below 75 microns. The pulverized coal is blown with part of the combustion air into boiler plant through a series of burner nozzles.
