The document describes the specifications of N.C.E. series water tube boilers. The boilers have advantages such as low capital cost, fully welded tubes, 3 pass design, rapid startup to save time and money, low heat emissions, and requiring small floor space. They also have high efficiency between 87-84%, are easy to operate and service, and have readily available parts. The boilers are available in various sizes from 150-1500kg/h and have dimensions and technical specifications listed for each size.

2. v LOW CAPITAL COST
v FULLY WELDED TUBES
v 3 PASS DESIGN
v RAPID STARTUP SAVE$ TIME
v LOW HEAT EMISSIONS
v SMALL FLOOR SPACE NEEDED
To Compare
N.C.E boilers specifications exceed the
minimum requirements of
relevant codes, and compare favorably
to other equipment that is available).
SPACE REQUIREMENTS
The N.C.E range of boilers being vertical down fired
design takes a minimum of valuable floor space.
OPERATING COSTS
Are minimized with the N.C.E boilers, the
3 pass natural circulation water wall design
will provide a guaranteed minimum of 80%
efficiency across the operating range of
boilers.
RADIATED HEAT is not a problem with N.C.E
boilers, high quality thermal insulation is fitted
to the boilers, ensuring a more comfortable
workplace, and increased energy efficiency.
QUALITY FITOUT of the N.C.E boilers
Has enabled a low cost low maintenance v QUALITY FITOUT COMPONENTS
steam boiler that will provide many years v EASY TO OPERATE
of reliable service. v EASY TO SERVICE

3. N.C.E Series
Water Tube Boilers
N.C.E is the registered product range of
steam generation equipment manufacture
by the New Challenger Engineering Services.
The N.C.E boilers have a standard design
pressure of 140psi, but are supplied fitted
out to client’s specification.
.
All N.C.E boilers are engineered to provide
a long service life with minimal maintenance
requirements.
N.C.E boilers carry a 12 months warranty
on the shell & tubes,
providing the boiler is operated and
maintained within relevant Standards,
including water treatment.
.
Today’s N.C.E range of packaged
steam boilers are the product of many years
of development, that has been heavily influenced
by market requirements, and loaded with features
and system options to meet the clients Specification.

The above specification is based on the following conditions.
-Steam pressure: 10kg/cm2
-Feed water temp : 20℃
-Low heating value for fuel
-Fuel gas supply pressure : 200±50mmH2O
The measured efficiency is based on low heating value when the boiler is operated in full power.
Measurement errors due to inevitable uncertainties are as follow.
Boiler efficiency error ±1%, heat input ±3.5%
220V/1￠ is required for soft water to be controlled separately from boiler control unit.
For better efficiency and performance of the products, slight modifications can be made without notice.
The heating value of fuel is based the following
13A(Natural Gas) High/Low : 11,000/9,900kcal/Nm3
