Characteristics of Structure

        The boiler body adopts double-drum, water tube structure and chain grate combustion mode. The drum is arranged longitudinally along the center of the boiler up and down, the wall of water tubes forms the radiant heating surface of the furnace, the tube group between the upper drum and lower drum forms another convection heating surface of the furnace; and a coal economizer is equipped on the tail of fume.

• The chain grate is separated into several bins for intake of combustion air with separately adjustable volume and the grate is infinitely speed-regulated. The combustion chamber above grate is heightened and is set up intakes of secondary air on side of chamber.

• A unique anti-wear structure is used by the convective and radiant heat exchange surfaces of the furnace chamber.

• The feeding device has complete intellectual property rights and adopts locking mechanism for materials.

• The overall structure of the boiler is compact, covers a small footprint, requires little assembly, short installation period and save installation cost.

Product Features

High Efficiency and Energy Saving

        The radiant heat exchange section adopts dense cold-water tubes or membrane wall structure of water tubes, the convection heat exchange section has type S multi-return heat exchange, and the tail is arranged with high-efficiency fin economizer for heat exchange that has high thermal efficiency.

The boiler adopts high-quality thermal insulation materials and special construction technology, with less heat loss, low exhaust temperature and high thermal efficiency.

To ensure that the fuel burns completely and evenly and that the combustion efficiency is good, the grate combustion chamber is heightened and equipped with secondary air that is helped by combustion.

The boiler warms up and starts quickly due to its reasonable arrangement of heating surfaces.

The grate and arch of the furnace have a special design, with the grate separated into several bins for air intake, and independently adjustable air volume, all of which make the boiler have wide adaptability of fuel.

Safe and Reliable

        Radiation heat transfer surface and convection heat transfer surface of furnace chamber is all arranged with a special anti-wear structure to increase the using life of boiler.

Feeding device adopts locking mechanism of material and using secondary air can effectively prevent flame backfire and burned-out hopper.

The boiler operation incorporates remote and local monitoring. A complete automatic control system and monitoring instruments ensure its safe, reliable, and straightforward operation. Establishing an Industrial Internet of Things (IOT) platform for industrial boilers, which integrates industrial automation control technology, Internet technology, computer software, and artificial intelligence technology, allows for remote human-computer interaction and data sharing, facilitating the control of our boilers.

Green and Environmental Protection

        We can select configurations cyclone separators, bag filters, DST (desulfurization towers), ESP and other EP equipment in accordance with local environmental protection regulations to make vastly fume emission to meet ultra-clean emission standards of Bangladesh. 

Special Technical Characteristics

            Possess all the high thermal efficiency, high safety, low environmental emissions and excellent technical performance of energy-saving gas boilers.

Biomass-fired boilers are especially adapted to be used in rural areas of Bangladesh where energy is scarce and biomass materials are abundant, and this boiler makes it possible to produce high-quality steam at very low cost in these areas.

The special structural design of the boiler allows the biomass fuel which enter the furnace chamber can be fired safely and efficiently without any fuel waste.

Together with biomass granule processing equipment and environmental protection equipment, the SZL series boiler can achieve the goals of high efficiency steam production and clean emissions of flue gas.

To guarantee that the boiler is operated safely and effectively, the centralized control system can provide warnings for water shortage, over pressure, flame out, and other limiting situations. It can also provide the necessary self-locks and interlocks.

Fuel selections

        Jute straw, rice husk, coconut shell, wood chips, tree branches and bituminous coal.
