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.

Specifically, AFUE is the ratio of annual heat output of the furnace or boiler compared to the total annual fossil fuel energy consumed by a furnace or boiler. An AFUE of 90% means that 90% of the energy in the fuel becomes heat for the home and the other 10% escapes up the chimney and elsewhere.

What is a Boiler and How does It Work? - YouTu

Aug 19, 2019· The design is fairly similar to a fire-tube boiler, but instead of the furnace heating fire tubes to heat water in a tank, the furnace heats water tubes inside the furnace. In the same way, a fuel

TerraSource Global | Boiler Fuel Feed Syste

Boiler fuel feed systems are made up of a combination of storage, reclaim, conveying and feeding equipment and are available in mechanical and pneumatic systems. Features of Boiler Fuel Feed System Jeffrey Rader boiler feed equipment is used for feeding biomass and alternative fuels, including woody biomass, agricultural or refuse derived fuels

Power A 2018 Chapter 12 Elements of Boiler Syste

A device consisting of a mechanically operated fuel feeding mechanism and a grate; used for the purpose of feeding solid fuel into a furnace, distributing it over a grate, admitting air to the fuel for the purpose of combustion, and providing a means for removal or discharge of refuse.

Boiler (power generation) - Wikiped

Author: EPCB Boiler A boiler incorporates a firebox or furnace in order to burn the fuel and generate heat. The generated heat is transferred to water to make steam, the process of boiling. This produces saturated steam at a rate which can vary according to the pressure above the boiling water. The higher the furnace temperature, the faster the steam production.

Husk Fired Boiler | Internal Furnace Top Feeding Boil

Husk Fired Boiler: Internal Furnace Top Feed Steam Boilers. Internal Furnace Top Feed Husk Fired Boiler is said so because of their unique automatic fuel feeding from the top of the Internal Furnace boiler.Until now automatic feeding was only possible in case of an external furnace where the furnace is not a part of the boiler.. Thermodyne Engineering Systems has a dedicated team of qualified

Furnace oil used in Boiler or Thermic oil heater can be totally substituted by Briquette with an equivalent ratio of 2.2:1 Kg/lit on the basis of calorific value.

Natural Gas Vs Fuel Oil Vs Propane: The Furnace/Boil

Apr 05, 2018· While market fluctuations and regional differences in price make deciding on a boiler or furnace fuel more difficult, there is value in looking at historical trends. Historic differences between fuel oil and natural gas can help consumers develop a general idea with respect to cost differences. Historic Natural Gas, Fuel Oil, and Propane Prices

Oil-Fired Boilers and Furnaces | Department of Ener

A time delay relay is a way to squeeze the most heat out of your system without running the boiler. When the thermostat clicks on, the relay causes the boiler to circulate hot water through the system without turning on the boiler. After a set time, the boiler will fire up. A time delay relay costs about $100 and can cut your fuel costs by up

Boiler Fuel - an overview | ScienceDirect Topi

The fuel feeding system in a PFBC can be either a slurry feeding or a dry feeding system. In the former, coal and additives (e.g., limestone) are mixed with water and then pumped in the combustion chamber; in the latter, coal is pressurized in a lock-hopper system and then transferred to the combustion chamber via a distribution hopper and
