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.
