Oil Fired Boiler Marine - China

General Description

Light oil or heavy oil is suitable for this boiler plant.

The boiler can be used for heat supply, oil heating and

daily life service.

Brief Introduction of Boiler Structure

The boiler body consists of boiler shell, furnace and pin

tubes with an all welded type structure.

The pin tube being

assembled inside theΦ219 or Φ273 smoke tube separately,

consists of closed-pitched columnar steel pins which are

welded on the outside surface of a steel tube.

The boiler

furnace is a full water cooling furnace consisting of a

cylindrical furnace and upper, lower end which increases

heat transfer efficiently.

The convection-heating surface of boiler consists of smoke

tubes and pin tubes.

The high temperature smoke from furnace

enters into smoke tubes, flush the internal surface of smoke

tubes and the pin tubes at the same time, forming a high

efficient convection-heat exchange tube group.

The setting & function of boiler accessories

a.

Main steam valve — on the top of boiler, which can

transfer the steam from boiler to steam main pipe.

b.

Safety valve — on the top of boiler, which can discharge

all the steam at full load when the boiler is over pressure.

c.

Water level gauge and water level controller — on the

steam-water interface, which is used for boiler water level

indication and for the supervision by boiler operator.

The

water level controller is used to transmit the value of

boiler water level.

The control system will control the

feeding water pump or do burner emergency stop according to

the signals received respectively.

d.

Feeding water stop valves and check valves — on the

shell side, one set for main feed water and another set for

standby purpose.

e.

Scum valve — to be used for draining off the suspension

of oil sludge.

f.

Blow down valve — to be used for draining off the

boiler’s deposition and dirt.

f.

Gauge valves — on the top of boiler, to be used for

connecting the instruments with steam inside the boiler.

g.

Air vent valves — to be used for discharge the air

inside the boiler when pressure is increased.

There are manholes and hand holes on the boiler shell in

order to maintenance the inside parts of boiler

conveniently.

In order to decrease the heat loss of boiler and to low the

surface temperature of boiler, the outside surface of boiler

should be packed with insulation material and covered with

thin galvanized steel plate.

Ⅲ, Boiler Working Principle

The furnace and smoke side of boiler tubes absorb the heat

produced by fired oil and transfer it to water, then the

water will be evaporated into steam.

Steam rise up and enter

the vapor space because its specific gravity is reduced.

The

space left by steam will be made up by water with a heavier

specific gravity.

This process forms a natural steam-water

circulation.

When the water level becomes lower because

water is evaporated into steam continuously, the feed water

pump will feed water into boiler to keep the water level in

the normal range.

This process continues and steam will be

produced continuously by absorbing the heat produced by

fired oil to heat water.
