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.

Is a boiler an internal combustion engine - Answe

Internal engine has its energy ignited in the cylinder. like 99.9% of engines today An external combustion example is a steam engine where the heating prosses is done in an boiler out side the engine.

Boiler/Burner Combustion Air Supply Requirements a

A clean and tidy boiler room, particularly in the area of the combustion air intakes and the burner air inlet damper, is paramount in maintaining proper combustion. Such things as newspapers or animal hairs on fan inlet screens, dirt-encrusted fan blades, and birds' nests in unprotected stacks have all been seen to contribute to sooting and/or

Boiler Room Air Supply - Johnston Boil

Boiler Room Air Supply The proper operation of any boiler is dependent on the systems that support and connect to it. These include, but are not limited to; the boiler room fresh air supply, flue gas exhaust system, fuel delivery system, power distribution grid, and the steam or hot water distribution system.

Combustion Air Requirements & Defects at Heating Equipme

Combustion air defects at heating boilers, furnaces, water heaters Diagnose signs of inadequate combustion air for an oil or gas burner Dangers of carbon monoxide poisoning if there is soot production at gas fired heating appliances Inadequate combustion air can cause dangerous carbon monoxide gas in buildings Combustion air safety check procedure for gas fired heating equipment How to test

Combustion Air Requirements:The Forgotten Element

Temporary air intakes such as open boiler room windows can be closed (and often are when persons in the boiler room are feeling cold), cutting off the boiler's air supply. When the combustion air supply is closed off, the fire starts to smoke as the air supply is exhausted. Incomplete combustion occurs and carbon monoxide is generated.

Boiler Combustion | CleanBoiler.o

Theoretically, there is no limit to the amount of NOx reduction with FGR; practically, there is a physical, feasible limit. The limit of NOx reduction varies for different fuels Ñ 80% for natural gas and 20-25% for standard fuel oils. The current trends with low NOx technologies are to design the boiler and low NOx equipment as a package.

Combustion Air: What Is It? Why Is It Important? - Ho

(2) The duct work installed to bring fresh, outside air to the furnace and/or hot water heater. Normally 2 separate supplies of air are brought in: one high (for ventilation) and one low (for combustion). Depending on the year of construction and the style of the dwelling, there are several ways in which combustion air is provided to the home.

Combustion Basics | CleanBoiler.o

Combustion Basics. Chemistry. Combustion is the rapid combination of oxygen with a fuel, such as natural gas, resulting in the release of heat. Most fuels contain carbon and hydrogen, and the oxygen usually comes from air. Combustion generally consists of the following overall reactions:

Low Pressure Boilers Ch. 5 Flashcards | Quizl

In order to bank a fire, the _____ is disengaged. coal feed. In an air atomizing burner, steam and fuel are discharged to the burner for combustion. False. The manual reset valve in the low pressure gas system closes if the boiler has a high water level. False.

Combustion Air Requirements for Gas Furnaces - Inspecti

Feb 07, 2020· Is there a quick and easy way to calculate how many cubic feet of combustion air a natural gas furnace in a room needs? This is assuming all the combustion air comes from that room. I know I’m not supposed to be out there making calculations like this. The reason I ask is every once in a while I run across a furnace in a room with out a source of combustion air (no flues or louvers in the

1.3 Fuel Oil Combusti

1.3.3.3 Nitrogen Oxides Emissions1-2,6-10,15,17-27 - . Oxides of nitrogen (NOx) formed in combustion processes are due either to thermal fixation of atmospheric nitrogen in the combustion air ("thermal NOx"), or to the conversion of chemically bound nitrogen in the fuel ("fuel NOx").The term NOx refers to the composite of nitric oxide (NO) and nitrogen
