DZL Series Chain Grate Packaged Boiler which is a vertical type with a single drum belongs to the traveling grate boiler. It is a high-efficiency and environment-friendly product that could easily burn shaped biomass fuel or both pure and mixed coal with its economizer in the rear that discharges the slag which could be used as fertile to agriculture. Equipped with forced-and-induced draft fan to ventilation and screw mucking machine to discharge the slag, this boiler has the full of controlling and monitoring meter instruments, so the operation of it is safe and reliable.DZL Series Chain Grate Packaged Boiler is fourth generation, Horizontal Water Tube and Fire Tube Package Boiler has the features of small occupation, bigger output, quick pressure, high efficiency and so on. We have patent rights to produce the boiler. It has been awarded as the following: national high quality product prize, provincial high quality product prize, city class high quality product prize, Provincial Prize for Progress in Science and Technology, etc.
The features of DZL Series Chain Grate Packaged Boiler are as follows:
1. Some of the rising tubes on two sides of steam header go up to the furnace, then go to down side of drum, together with the mason work insulation heating surface there, all these form the boiler top heating surface. By adopting of this novel furnace structure, we tackle the deficiency of "bulge" which is happen because of direct heating the down side of the drum.
2. By adopting of double wings gas ducts, the fuel gas can go into the front gas tank easily, so the temperature of different front plates can be same. In this way, it can avoid the crackles happening in the plates.
3. Spiral tubes are installed in the drums, which can strengthen the heating transferring efficiency, at the same time, spiral tubes have the ability of dust removal, which can avoid the dust stratification in the tubes.
4. Both of the front and the back arches of the 10t/h series boilers adopt mason work of water cool tubes wall structure, which can form permanent arches.
5. There are separate adjustable wind chambers,wind is feed from two sides.It adopts new type crank screw wind adjustment structure,so that the wind adjustment and ventilation cross section proportion is 100%,which can ensure the easy wind adjustment and make it symmetrically. DZL Series Chain Grate Packaged Boiler can meet customers' demands.
