2. Description
2.1. General information
Ensbury LT boilers are high efficiency, power- saving low
temperature boilers ranging from 70 to 580 kW and from
65 to 500 kW for low-NOx applications. They can be
operated in combination with oil or gas burners.
Ensbury LT boilers are three pass, smoke tube boilers with
combustion chamber and flue way using the Low-Nox
technology. 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 PYROFLOW system simplifies the conception of the
installation and considerably improves profitableness and
reliability.
The idea behind the PYROFLOW system is to heat the cold
return water by means of internal heat exchange and mixing with
the warm boiler water.
The cold return water is fed to a distributor (1) and from there into
collector (2), which completely encapsulates the internal supply
pipe (3). The return water is preheated within this collector.
Calibrated holes (4) all along the bottom of the collector guide the
water towards the furnace while preventing any contact with the
flame tubes. The hot furnace surface further heats the water,
which is consecutively mixed with the boiler content.
The supply temperature is governed by means of the numerical
Ygnis governor, which pilots the mixing valves of the hydraulic
units, or in case of cascades, the closing valve of the boiler in
question.
The symmetrical geometry of the boiler and the large water
volume assure a homogeneous temperature distribution and an unhindered natural convection.
This concept, coupled with the Ygnis patented flame escape system, also allow users to obtain low emission
values and safe operation in conformity with law provisions.
The boiler’s thermal insulation is made of glass fiber felt that adheres to the boiler shell, guaranteeing minimal
loss in stand-by mode.
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.
In addition, the front part of the boiler is provided with superior quality ceramic fiber insulation. 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 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 a environment-friendly paint,
so they are permanently protected from corrosion.
A divided version of the boiler range can be made available as custom made option. Thanks to the inferior
dimensions of the individual parts, this version is most suitable when bringing-in conditions are tight. The
individual prefabricated parts must be welded together in the boiler room.
2.2. Conformity and certificates
This boiler fulfills the requirements of the low voltage directive 2014/35/EU, of the EMC-directive 2014/30/EU
and the efficiency directive 92/42/CE for low temperature boilers as well as the
GAR 2016/426
.
The boiler range with ECA-rating has efficiencies in conformity with the requirements of the Enhanced Capital
Allowance Scheme (ECA).
The Directive
2009/125/EC
and its rule of application EU 813/2013 of 02 August 2013, laying down the
requirements of eco-design applicable to devices of heating premises, relates only to the product
s ≤ 400
kW. Based on this:
The Ensbury LT Models 70 to 370 are not intended for heating the premises,
The Ensbury LT models
440
to 580, which are not affected by these requirements, can be used for
heating premises.
