>> Introduction
SZW series coconut shell boiler is a double-drum water-tube steam boiler. The boiler is divided into two parts: the upper body and the lower combustion equipment. The upper body of the boiler is composed of upper and lower drums, water-cooled walls connected to the left and right headers, and a convection tube bundle between the upper and lower drums. The inside is a furnace wall made of refractory bricks and refractory concrete and front and rear arches; the outside is a steel frame and Skin board, with insulation material in the middle.
>> Features
Small footprint

1. Small footprint

Compact structure, small floor space, single-story layout of the boiler room, and low capital investment.

2. Short cycle

High degree of assembly, short installation period and low installation cost.
Small footprint
High thermal efficiency

3. High thermal efficiency

The heating surface is fully and reasonably arranged, the boiler heats up quickly, the pressure rises quickly, the output is sufficient, and the thermal efficiency is high.

4. Fully burn

The grate is divided into air chambers for air intake, each air volume is independently adjustable, and the furnace discharge is steplessly adjusted to achieve full combustion.
Fully burn
