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.

What is combustion efficiency in steam boiler?Managing your boiler with the best amount of excess air will reduce heat loss up to the mass and enhance combustion efficiency. Combustion efficienWhat are the factors of combustion efficiency?The thermal efficiency and combustion efficiency of a condensing device will be different. The only way to determine the exact thermal efficiencyWhat are direct and indirect efficiencies in boiler?The overall boiler efficiency relies on many parameters apart from combustion and thermal conductivity. These other parameters include ON-OFF damag A general investigation on modeling, identification and control of the coal fired thermal power plants are provided by Sreepradha et al. . Subsequently, authors recommended for the improvement in efficiency of overall power plant by performing proper studies on the material balance and energy balance of …
Boiler Efficiency Improvement Steps: After Analyzing heat losses in industrial boilers, boiler engineers or technicians can help you to increase your boiler efficiency by 6% – 10%.. Here are the few boiler efficiencies boosting steps listed below:. Complete combustion of fuel so that no unburnt is left behind is a good practice and will add to the boiler efficiency.
The reason is that the heat released by the additional thermodynamic cycle is recovered in the boiler drum of the original thermal power unit. Thus, the boiler thermal load for power regeneration mode can be expressed as (11) Q b ′ = 1-α adl Q b + α adl Q b-D 0 q 2,adl = Q b-α adl D 0 q 2,adl
A form of heat power using a vapor pressure is fired into the turbine so that it will cause a rotating force that will turn the generator of an electric generator. thermal power has the ability to
Mar 15, 2020· In coal thermal power plant, the steam is produced in high pressure in the steam boiler due to burning of fuel (pulverized coal) in boiler furnaces. This steam is further supper heated in a superheater. This superheated steam then enters into the turbine and rotates the turbine blades. The turbine is mechanically so coupled with alternator that its rotor will rotate with the rotation of
This is the pump peculiar to the forced circulation type boiler. This pump is necessary for protection of the cooling pipe of the furnace. It circulates water in the cooling pipe of the furnace when starting the operation and at low load and always maintains the flow in the pipe approximately at a fixed speed.
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
Author: Ruifeng Cao, Yue Lu, Daren Yu, Yufeng Guo, Weiwei Bao, Zhongbin Zhang, Chuanxin Yang The recovery boiler plays a central role in the chemical cycle of a modern kraft pulp mill and generates energy for the mill. Turbogenerators for thermal power plants, power generation systems for the efficient use of traditional fossil fuels as well as biomass, process gases, black liquor, and refuse-derived fuels. activities focus on
Feb 15, 2015· With reheat, a power plant can take advantage of the increased efficiency that results in higher boiler pressure and yet avoid low-quality steam at the turbine exhaust . Habib and Zubair [ 3 ] conducted a second law analysis of regenerative Rankine power plants with reheat.
