The shell is 1600 mm, the water wall on the left and right sides of
the furnace is a radiation heating surface, and the bottom of the
furnace tube adopts a new cross-arrangement technology of 1600. The
cylinder is 160.160, the furnace wall is made of heat-resistant
concrete, and the outside of the furnace is three-dimensional.
Boiler body is symmetrically arranged from top to bottom, water
wall tube is 160, coupling tube is 160, cylinder is composed of
1600 *14 tubesheet. Boiler tubes are 57X-3, 159x6, 133x6 and 160.
There are front and rear brackets in the boiler. The combustion
efficiency is high.
Product Features
1. Installation convenience:
The boiler is generally fast-loading factory, easy to transport and
on-site installation, greatly shorten the construction cycle.
2. Reliable operation:
Boiler heating surface layout is reasonable, water circulation is
smooth, and each heating surface is cooled in time.
3. Maintenance and repair convenience:
It is convenient to open the smoke box in front of the boiler, and
the personnel can check it easily and clearly, which provides a
good condition for correct treatment.
4. Full combustion:
With the secondary air and reasonable furnace design, the fuel can
be fully burned and the black smoke can be eliminated.
5. High efficiency grate:
Boiler grate adopts double side ventilation, which is brought
naturally to the front end of boiler row by dust cleaning
technology, and is easy to operate, and has obvious advantages
compared with ordinary grate.
6. Convenient ash cleaning:
Many ash cleaning holes can be set up on the boiler, which can
remove ash in time and effectively, avoiding the trouble of
operation and decrease of thermal efficiency caused by boiler ash
accumulation.

Note: the fuel consumption in the table is calculated on the basis of
the low calorific value of biomass particles 17084KJ/Kg
(4085Kcal/Kg). If the low calorific value of biomass fuel is larger
than this value, the corresponding fuel consumption will be more
economical than the value in the table.
