SZL series coal-fired hot water boiler

SZL series coal-fired hot water boiler

Advantages

1, The advantage of the boiler sucking the quick-loading boiler is that the upper body is large and the lower part consisting of the chain grate and the coal hopper. The two large parts can be operated only after the construction site is closed, so the installation is convenient , short cycle, cost less.

2, The boiler has a compact structure and a small floor space. The boiler room only needs to be arranged in a single layer, so the investment in civil engineering is small.

3, The boiler is easy to operate, stable in operation, fast in heating and boosting, and has sufficient output to adapt to a wide variety of coals.

4, complete supporting machine, drum fan, water pump, gear box, dust collector, etc. can meet the boiler load requirements.

5, the boiler is equipped with a complete set of thermal testing instruments, electronic control console, drum fan opening, and grate speed can be remotely operated.

6, The boiler air supply system adopts a split-type double-side air supply device. Each air chamber can be independently adjusted, with small air leakage and strong adjustability, which can better meet the requirements of the combustion characteristics of the chain grate.

7, Good environmental performance, low boiler emission concentration and low blackness, which can meet the environmental protection requirements of the national first-class regions.

Overview

The boiler type is a double-drum longitudinal chain grate. The boiler has a compact structure, small footprint, and the shape is packaged with a shaped guard plate. The novel design is beautiful and the appearance is elegant and single-layer (also can be double-layered). For the upper and lower parts, the large parts are shipped. It is divided into upper and lower bodies. The upper body is mainly composed of a water cooling system, an upper drum, a lower drum, an upper drum inner device, an upper body bracket, a steel frame and a guard plate, a furnace wall and an internal masonry part of the heat preservation. The lower part is a high body grate.

The boiler is equipped with a water-cooled wall of the light pipe on both sides of the furnace, and the convection tube bundle is arranged on both sides of the upper and lower drums to adopt the "S"-type flue gas direction, the heat exchange efficiency is high, the dust removal effect is good; the air is distributed in the warehouse to facilitate the adjustment of the combustion; Ample area and good burning.
