Wood Fired Steam Boiler DZL Type Chain Grate Stoker

Wood Fired Steam Boiler Introduction

As the name suggests, Wood Fired Steam Boiler uses biomass energy as a fuel. It can be divided into biomass steam boiler, biomass hot water boiler, biomass hot air furnace, biomass heat conduction oil furnace, vertical biomass boiler, horizontal biomass boiler.

What Are Our Wood Fired Steam Boiler Advantages And Characteristics?

The characteristics of wood fired steam boiler are as follows:

1. Yongxing boiler adopts the combustion equipment most suitable for biomass fuel combustion -- active grate, chain grate, or traveling grate.

Normally we suggest customers use chain grate, which can realize the mechanization and save manpower, reduce the project cost accordingly.

In terms of the structural design of the boiler, compared with the traditional boiler, the furnace space is larger, and the layout of the secondary air is very reasonable, which is conducive to the full combustion of the instantaneous precipitation of more volatiles during biomass fuel combustion.

The control system adopts high brightness, full English display, with a famous PLC control system as the central control unit;

Exchange information with boiler users through man-machine dialogue to realize the full automatic safe and reliable operation of biomass pellet boiler.

The biggest characteristic of wood fired steam boiler is energy saving, environmental protection, and ease to install and use.

2. Fuel supply

wood fired steam boiler's fuel is Biomass fuel, which is sent to the top hopper by the feeder, and then sent to the furnace chamber by the screw feeder, which is evenly scattered on the grate.

3. Combustion process

Fuel is sent to the furnace by the screw feeder, here due to high-temperature smoke and the effect of wind gradually preheat, dry, fire, combustion, this process precipitated a large number of volatile, burning violently.

The generated high-temperature flue gas scours the main heating surface of the boiler and enters the economizer and air preheater of the heating surface at the rear of the boiler then enters the dust collector and finally displaces into the atmosphere through the chimney.

The side of the gasified fuel moves towards the back of the grate until it burns out, and finally, a small amount of ash falls into the slag hole behind the grate.

4, Wood fired steam boiler environmental protection emissions

The ash produced by BMF combustion accounts for about 1.5% of the fuel. In order to facilitate ash removal, the rear of the boiler is equipped with a screw slag extractor to realize continuous ash removal. Dust remover is arranged in the flue of the rear of the boiler to ensure that the smoke emission meets the requirements of environmental protection.

5, Wood Chip Steam Boiler Efficiency

The efficiency of wood chip steam boiler is generally more than 80%, the boiler model is large, more fully burned, the efficiency of the boiler is higher. The highest was 88.3 %, 15% higher than the average efficiency level of coal-fired boilers.

What Is Your Design Of Your Wood Steam Boiler For Sale?

Compared with other boilers, the wood steam boiler has the following four advantages

1. A multi-purpose furnace, heating at the same time can cook, boil water, bath.
2. Super conversion system, start the heat transfer temperature is low, heat transfer speed is fast.
3. Low installation cost, heating safety: the equipment is universal, do not change the original heating equipment, pipes, radiators are universal, the use of water cycle to achieve a wide range of heating materials sources, never exhausted, everywhere desirable (such as rice husks, corn stalks, rice straw, wheat).
4. Safety and environmental protection: low working pressure, no, cooking, boiling water, bath, heating, etc., also suitable for boiler burning, greenhouse heating, large-area heating, small and medium-sized hotel use, not subject to seasonal restrictions, can be used throughout the year.

Users exchange information to realize the fully automatic operation of the BMF boiler.
