2.  Description 

 

2.1.  General information 

Melbury HE boilers are high efficiency, power-saving boilers ranging from 530 to 3000 kW and from 450 to 2600 

kW for low-NOx applications. They can be operated in combination with oil or gas burners. 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The third pass is equipped with turbulators. Their turbulent action further increases the heat exchange and allows 

the system to work at low combustion gas temperatures, guaranteeing optimal fuel use as a result. 
The boiler’s thermal insulation is made of glass fiber felt that adheres to the boiler shell, guaranteeing minimal 

loss in stand-by mode. In addition, the front part of the boiler is provided with superior quality ceramic fibre 

insulation. The outstanding characteristics of the material are the low thermal conductivity and the low specific 

thermal capacity. This leads to a further reduction of the stand-by losses. 
A soundproofing hood can be optionally provided that covers the whole of the front of the boiler, with which 

burner noise can be kept down to a minimum and thermal radiation can be further reduced. 
A revolving door gives easy access to parts of the boiler that are in contact with combustion gases. This allows 

cleaning of combustion chamber and passage ways to be easily performed from the front. The turbulators are 

retractable from the front. The combustion gas collector on the rear of the boiler is provided with an opening for 

easy cleaning. 
The boiler’s thick casing is easy and quick to install. Casing plates are painted with an environment-friendly paint, 

so they are permanently protected from corrosion. 
 
 

 

The Melbury HE, C version is equipped with an 

integrated flue gas recuperator made of special 

stainless steel that is also designed for operation 

with oil and/or gas burners. In this combination, the 

Melbury C becomes a condensing unit that uses the 

condensation heat of the steam present in the flue 

gases. As a result, the efficiency can increase to 

over 107% (in relation to the lower calorific value) at 

a correspondingly low return temperature. 

 

 

 

 

 

 

 

The Melbury HE boiler range are three pass, smoke 

tube boilers with combustion chamber and flue way 

using the Low-Nox technology. The geometry of the 

furnace, the furnace’s low charge, coupled with the 

Ygnis patented flame escape system, allow users to 

obtain low emission values and safe operation in 

conformity with law provisions.
