Detailed description of coal steam boiler

1. Adopting automatic screw feeding, with reasonable second air technology and half gasification structure helping fuel combusting completely, the thermal efficiency can reach more than 90%. Stable flame, producing steam cautiously. 

2. Environmental biomass fuels are widely promoted by the state because it’s cheaper price and wide sources. Operating cost is One-sixth of electric boiler, one-third of oil boiler.

3. Control system: Installing microcomputer to operate with one-button, people just set the process, and it can work automatically during the operating time. Once any abnormal situation to happen, stopping automatically with sound-light alarm, and pointing to the failure code, so it saves time to maintain.

4. Our protected device is safe and reliable. Selecting superior pressure controller, safety valve, low water alarm, overpressure alarm, over-temperature alarm, in order to make boilers operate safely.

5. Reasonable over-all structure to cover little space, hearing no sound. It is easy to install, because there is no need to set up tall chimney, with a very low failure rate.

6. It is simple to clean slag only after burning completing.

Working principle:

 

Taida series air-cooled chain grate stoker is an efficient, smokeless coal burner which is suitable for use with wide range of fuels, particularly smalls. The grate is renowned its supreme air flow characteristics. Different grades of grate links can be supplied depending on the fuel quality.

The stoker features the unique firebreak unit, which eliminate the danger of burnback in any condition, including shutdowns and emergencies. Water-cooled side cheeks, and the unit's ability to interface with Building Management System, create an unprecedented degree of automation, and make substantial cost savings possible.

When the size of the combustion units is transportable, We pours the refractory inside its combustion chambers in the shop.  Field installation time can be cut back considerably by having the refractory installed in the shop.  Most vendors have the refractory installed on site were quality assurance can become an issue.  In this case, we can send professional and experiences workers for pouring the refractory in site.
