Basic Introduction
DZL series coal fired boiler stands for single drum horizontal chain grate boiler. It is a packaged water&fire tube boiler, three pass flue gas, wet back design, with grate stoker for fuel burning. Automatic feeding, automatic slag removal, Interlocking alarm, only one worker can operate it well.
DZL boiler has the features of "two wings-shape flue" "convex tube plate" "furnace arch" "inertia gas-dust separation" etc, realize high efficiency and low emission. It's called as "Revolution of Industrial Boilers" by China and overseas markets.
Know the fuel analysis. Different fuel moisture and calorific value determine the internal design of the boiler, as well as the selection and configuration of the grate, feeding method, air distribution, slag discharge, etc.
Packaged boiler shipped, quick installation. After the boiler arrived, only need to install the valve, instrument, water system, electricity system and pipeline, then boiler can be put into operation.
Characteristics
01
Three pass gas flue structure & Arched tube plate
1. Three pass design extends the flue gas distance, strengthen the thermal transfer efficiency; 2. Arched tube plate increases the toughness of the tube sheet, prevent end cover cracking
02
Spiral Fire Tubes(Smoke Tube) Technology
Use the advanced technology which is our patent to design the spiral tubes, to enhance the boiler thermal power 10% higher than normal, and avoid the spiral tube from ash deposition and wearing
03
Fully automatic chain grate combustion
Use big piece fire grate, air supply sufficient and evenly, tight connection, almost no leakage, avoid loss of calorific value and affect boiler thermal efficiency
04
Economizer Design, Energy Saving
1. Recycle exhausted smoke to heat feed water, increase feed water temp then save fuel cost at least 6% per hour 2. Reduce chimney smoke temperature
