The gas oil water heating boiler is popular in hotels, greenhouse
central heating, office buildings, city central heating, hospitals
as well as all other industries that need hot water heating.
The vacuum hot water heating boiler’s half bottom is similar with
ordinary boiler, combined with combustion chamber and heat transfer
tubes. The inner part is the media hot water, and rest empty part
is air, with an U tube works as heat exchanger. The water heating
boiler runs under the condition of negative pressure, and it
absolutely ensures the operation safety.
1. Safe and reliable: because its medium circulation system
pressure below the atmospheric pressure, the vacuum hot water
boiler unit running internal absolute pressure is 0.02 ~ 0.08 MPa,
and unit is in the vacuum state, so there is no risk of explosion.
2. Multiple usage: a set of hot water heating boiler can configure
multiple heat exchanger, different temperature, different uses of
hot water, such as central air conditioning, sanitary hot water,
process water, etc.
3. High thermal efficiency: with three-pass structure, large
heating surface, unique wet back combustion chamber structure, the
boiler can significantly reduce heat losses, and overall thermal
efficiency can be up to 92 %. No fouling in furnace makes the
boiler maintain years high efficiency operating.
4. Long Service Life: No scaling inside the boiler increases its
service life, the life is generally 1.5 to 2 times of other heating
boilers. Heat exchanger made of stainless steel tube is resistant
to corrosion, the design life is more than 20 years.
5. Accurate control: According to outside load change, it can
automatically adjust its operation, hot water temperature can be
set freely between 20 - 90 ℃, then the unit can automatically
adjust the temperature, to ensure a constant temperature.
6. High standard configuration: Boiler combustion and control
system components adopt imported high quality accessories. Brand of
burner: WEISHAUPT(Germany), BALTUR, RIELLO(Italy). SEMIENS Touch
Panel, PLC controller. All the configuration can realize low
operation maintenance cost, automatic control and good boiler
7. Environmental friendly heating boiler: fuel complete combustion,
low dust emissions; secondary combustion, effectively inhibited NOX
generation; low burning noise, low pressure in chamber.
