esta Responds To

Regulations For Ship-

J Incinerators ub-committee on Ship Design

Equipment under the IMO has zed a draft for standards for

Dboard incinerators for dis- i of ship-generated waste." Del- ions from Denmark, Germany, way, Sweden and the U.K. par- >ated under the chairmanship .le U.S. i/S Vesta, founded in 1914, and

Lcb now manufactures two main iducts, heat exchangers and in- erators, received a copy of the aft a couple of months ago for aluation purposes. With envi- nmental protection on the top of eryone's list, A/S Vesta custom- 's, shipyards and shipowners, ave been increasingly question- lg the company about the expected iew rules for incinerators and the ompany's ability to comply with ,hese.

The company reports that the most important features in the new rules are already a part of the de- sign and working principle of A/S

Vesta products.

Three measures taken to tighten the rules focus on quality control within the producing company, re- quirements for obtaining a Type

Approval Certificate from the IMO and requirements for emissions.

From A/S Vesta's viewpoint, it is surprising that no "after burner" or secondary combustion chamber has been recommended. For fuels with a high content of volatile matter, like waste, secondary air is very important in the destruction of or- ganic carbon.

It is known that, even after a good burn-out, carbon-containing species of low molecular weight (such as CO) will be able to recom- bine on particle surfaces under the influence of chlorine and catalyti- cally active metal salts present in the fly ash. This mechanism will form dioxins at temperatures be- tween 250- and 400-degrees Centi- grade. To prevent secondary for- mation of harmful species, the flue gas should be cooled to 250 degrees

Centigrade, not 350 degrees as sug- gested.

A/S Vesta has more than 50 years of experience in the marine mar- ket. In 1987 A/S Vesta took up the production of incinerators, when it acquired the rights to the design, production and sales of the ASI/

ASWI models from Atlas Danmark.

In 1988 the rights to the Combi

Turbon-incinerator were purchased from Ildolet. Since the autumn of 1991, A/S Vesta has been a mem- ber of the Aalborg Ciserv Interna- tional Group. The objective of A/S

Vesta is to supply incinerators which can meet the demands made to environmental protection both at sea and on land.

The Kelvin Hughes NUCLEUS Series Color ARPA

Radars are redefining the modern radar for the shipping industry.

The NUCLEUS Color ARPA combines innovative target tracking/plotting and integrated data acquisi- tion capabilities with speed, accuracy, screen defini- tion, ease of operation, and highest reliability. To overcome rows of confusing buttons and controls, this ergonomically designed, color ARPA utilizes a simple backer ball and three push buttons for all operations, making it one of the fastest, most user- friendly navigational radars on the market today.

Functions are selected by simply clicking a but- ton after moving the pointer with the tracker ball through the easy-to-use, on-screen menus. The high definition display provides a superior color radar picture with very sharp target contrast. The data displays clearly show operating functions, warn- ings, target information, and integrated own-ship navigational data.

The NUCLEUS Series offers five choices of dis- plays, NUCLEUS 6000 A (ARPA), 6000 T (true motion) and 6000 R (relative motion) Color Radars with 26 inch display; and NUCLEUS 5000 T (true motion) and 5000 R (relative motion) Color Radars with 20 inch display. NUCLEUS features powerful

X-Band and S-Band transmitters in different configurations. the new definition of modern radar!
