CDZL Boiler is Single drum, automatic fuel feeding, automatic water
feeding, automatic ashremove
Fuel for CDZL hot water boiler : Coal, biomass, rice husk, wood
pellet, staw pellet, saw dust, wood waste, peanut shell
This hot water boiler adopt chain grate,suitable for molding pellet
fuel,can add a small amount of wood,wood block,also can burn with
coal.
This hot water heating boiler adopt the newest achievements in
scientific research, such as:Arched Tube plate, thread smoke tube
etc, solve the tube plate crack of shell type boiler, Water wall
tube burst, low efficiency, insufficient of power,Poor pf coal type
adaptability etc.

Details Inside the Boiler:
Chain Grate: Strong, high temperature resistant, chain grate bar is
close connect, the coal or other fuel can not draw down .
Smoke Tube and water tube: Enough smoke tube and water tube, make
the boiler high efficiency. the smoke tube can be cleaned
easily.
The boiler have man hold and hand hole, which make the boiler easy
to maintain and repaire.
Welding: Our boiler use the advanced seamless welding
technology.
Design: the most suitable design, make the boiler easy to install
and operate.
Boiler Advantage
1. Lower dust emission & SO2 emission & NOx emission, dust
emission concentration < 30mg/m3
SO2 & NOx emission concentration < 18mg/m3.
2. We supply 2 units Water Pump (one duty one standby) which from
the famous pump manufacturer.
3. Boiler can achieve automatic temperature control & pressure
control & feed water control & feed fuel control &
safety indication. We also freely supply you a set of inner parts
of Electric controller for standby.
4. Boiler with stainless cladding, anti-corrosion & anti-rust
& beautiful appearance.
