ARTEMIS

Reverse flame tube boilers for hot / superheated water.Capacity range: 35.000 3.000.000 kcal/h

High efficiency.

The flame produced by the burner develops in the furnace.

Produced flue gases return towards the front and enter the tube

nest through the smoke chamber in the door. On leaving the tube

nest, flue gases are collected in the rear box and transferred to the

chimney.

The bottom of the boiler is arched and not flat as is common in the

market. This geometry ensures greater tolerance to mechanicalstress and better heat transfer.

High water volume in combination with a sophisticated design

ensures good water circulation and prevents from scaling.

Insulation with high density mineral wool protected with stucco

aluminium cover sheets.

Three-pass flame tube boiler for hot and superheated water.Range Capacity : 500.000 8.000.000 kcal/h

Durability.

These boilers have a three flue gas pass layout, the first of which

passes through the furnace. Produced flue gases are reversed in the

rear wet reverse chamber and return towards the front through the

tube nest of the second pass.In the front smoke chamber flue gases

are reversed again, enter the tube nest of the third pass and are then

collected in the rear box and transferred to the chimney.

The gas reversing chamber is water rinsed, while its design allows not only the smooth reverse of flue gases towards the tubes of the

second pass but also its easy visitation when it needs to be cleaned

or serviced.

ARTEMIS economizers can increase the boiler efficiency by 5-7%

using the flue gas energy that is released unexploited in the

atmosphere.

This energy builds up the temperature of the return flow water so

the efficiency of the boiler can reach 96%.

ARTEMIS economizers are especially designed and can be applied

to both new and already existing boilers.

Finned tubes of high quality

Large inspection openings Easily removable and pre-mounted to the flue gas rear chamber.

ECONOMIZERS

ARTO HN TYPE WATER-BOILERS

Hot water boilers with an integrated stainless steelwater heater.Capacity range : 50.000 500.000 kcal/h

A compatible burner is adapted to a steel made

combustion chamber. The flue gasses pass through

fire tubes and heat up the DHW which is insidea stainless steel tank with corrugated walls.

The fact that the DHW tank is hanged from the top

bottom of the boiler ensures that there is no

accumulation of scaling. This plays a vital role to

the long life of the boiler.

SOOT ACCUMULATORS

When the fuel used is heavy oil, then the flue gases except for their

high content in soot usually also contain unburnt masses which are

particularly damaging for the atmosphere and the environment.

A solution to this problem are soot accumulators, which through a

special layout of fins retain a big part of the soot and unburnt

masses and as a result the gases driven to the atmosphere are

cleaner.

Because heavy oil has high content in sulphur which is particularly

corrosive the soot accumulators are made of stainless steel sheets.

Durability

BOILER DOOR

One of the most important characteristics of a reverse flame

boiler is its door support.

In most cases a hanging of the door is observed and as a

result maintenance becomes hard and oen a leak of smoke gas

appears.

The support of the door of the ARTEMIS

PRN/W boiler is very carefully designed.

Despite its particularly big weight, it can

be closed even by a little child and no

sign of hanging will ever appear.

Smoke gases coming from the

tube nest are reversed through

the hollow in the door

insulation.

Special insulating materials

cut radiation losses to an

insignificant minimum.

FLUE GAS CHAMBERS

PRN/W

Alternatively the flue gas

connection duct can be

flanged and also arranged on

the top

The rear gas chamber is dismountable in all sizes of PRN/W and

SCOTCH/W type boilers.This makes maintenance and service a simple

procedure.

There in the flue gas chamber is also welded the flue gas connection

duct to the chimney. The connection is made by a carefully designed

coupling.

In big sized SCOTCH/W boilers (over 3.000.000 kcal/h) the rear smoke

gas chamber is welded to the boiler plate. However, it bears two

spacious ports which allow the cleaning of the boiler as well as easy

access to the rear boiler plate.

The flue gas side inspection opening bears a fireproof lining suitable

for temperatures up to 1900 C, which ensures easy access to the

furnace.
