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.

Boiler Study Guide Flashcards | Quizl

A device located a little above the NOWL that shuts off the boiler burner in the event of low water, preventing burning out of tubes and possible boiler explosion Main Header That part of the system which connects boilers in the battery and then distributes the steam to wherever it is needed.

BOILER EFFICIENCY GUIDE - Cleaver-Broo

incorporated into the boiler. Reviewing some add-on devices if the boiler is designed for optimum flue gas velocities in the first place. Each boiler pass should be minimizing performance robbing soot build-up within the tubes. When it comes to efficiency, the proof is indeed in the number of passes and optimized boiler pass design. 2

What Is a Boiler Feed Water Treatment System and How Do

Sep 26, 2016· For industrial companies using a boiler for its facility, some type of boiler feed water treatment system is usually necessary to ensure an efficient process and quality steam generation. The most appropriate boiler feed water treatment system will help the facility avoid costly plant downtime, expensive maintenance fees, and boiler failure as a result of scaling, corrosion, and fouling of the

Water Tube Boilers vs. Fire Tube Boilers - Miura Boil

Difference in Steam Boiler Design. Water turns to steam when it comes into contact with sufficient heat. From a design standpoint, water tube boilers and fire tube boilers have completely opposite approaches in how this contact happens. In a fire tube design, hot flue gas travels through tubes that are …

Water-tube or fire-tube condensing boiler, which is t

These tubes are surrounded by a water jacket. The heat from the hot gases transfers through the walls of the tubes and heats the water. In a water-tube boiler, the water is in the tubes while the fire is external to the tubes. The hot flue gases pass around and between the tubes…

How Water Tube Type Steam Boilers Work - Miura Boil

To answer this question effectively, we must first understand the main difference between the water tube and fire tube boiler systems. It all comes down to the relationship between the water and the heat source. With the fire tube boiler design, the water surrounds the heat source. In a water tube design, the heat source surrounds the water.

Water Tube Boiler - Construction, Operati

Jun 10, 2017· Due to continuous heat supply, some of the water gets vaporized into steam inside the tubes and a mixture of water and steam enters the boiler drum through the uptake header. The cold water from the boiler drum comes down through the uptake header and enters the lower end of the water tubes for getting heated further.

Problems in Boilers – Marine Stu

May 22, 2015· This white hot fire spread throughout the boiler melting and burning most of the tubes, and also initiated soot fire in the air heater. Water wall and screen tube headers were subsequently found to be blocked solid with plugs of steel which had formed when the molten boiler tubes and run back into …

Fire Tube vs. Water Tube Boilers - Honiron Manufacturi

Dec 07, 2016· Fire Tube Boilers. Fire tube boiler date back to the industrial revolution, where they were used in steam engines, both for locomotives and industrial plants. They work by circulating hot gas through tubes, which in turn run through a water tank. The water is heated and eventually turns into steam, which is then used to generate energy.

HVAC Training; This is how a Fire tube Boiler Wor

Nov 09, 2011· The heat produced by the gases of combustion pass through the tubes while the water surrounds the tubes. However, fire tube boilers have different designs like 2 pass, 3 pass, and 4 pass based on application and installation considerations. Fire tube boiler tubes are always measured by their outside diameter (O.D.).

Types of boilers, Fire tube, water tube and combinati

May 02, 2020· In the water tube boiler, boiler feed water flows through the pipes into the drum. The circulated water is heated by the combustion gas to form steam in the steam area in the drum. This boiler is chosen if the steam demand and steam pressure are very high as in the case of a boiler for power plants. A very modern water tube boiler designed with
