The wall seal blower in a Circulating Fluidized Bed Combustion (CFBC) boiler serves to maintain a proper seal between the combustion chamber and the external environment. By creating a slight negative pressure, it prevents the escape of flue gases and ensures efficient combustion by maintaining the required airflow. Additionally, it helps to enhance the overall efficiency of the boiler by optimizing the circulation of the bed material and improving the combustion process.
A waterwall in a boiler is any furnace wall that is comprised of refractory and tubes in a water-tube boiler. The tubes are evenly spaced and generally connect to headers which in turn are connected back to the main generating bank of the boiler. They serve a two fold purpose here in that they capture heat that would otherwise escape to the atmosphere and help heat the water in the boiler. And they also help keep the refractory cool (relatively speaking) This prevents spalling of the refractory.
A tangentially fired boiler has between 4 and 8 burners, placed in the corners of the boiler. These are sometimes angled vertically to maximize impingement of the flames. They are fired into the center of the boiler, not directly into the center, but at the wall to adjacent to them. This causes the flames to swirl inside of the boiler, causing an even distribution of flame throughout the boiler. This is shown pretty well here: http://www.alstom.com/power/coal-oil/utility-boilers/firing-systems This website also has a lot more detail than previously provided.
Clinkers, also known as slag, consist of the noncombustible elements and minerals found in coal that melt and fuse together as lumpy ashes from coal combustion. Boiler operators consider clinkers to be miserable stuff

You have air in the system you need to bleed it out. do you have a really old heater/ boiler. hot water heater need more info
To install a wall heater, first choose a suitable location on the wall. Make sure there is proper clearance around the heater. Next, mount the heater on the wall using the provided hardware. Connect the heater to the electrical supply following the manufacturer's instructions. Finally, test the heater to ensure it is working properly and safely.
"MTW" stands for "Minimum Tube Wall." It is a specification used in boiler tubing to indicate the minimum thickness of the tube wall required for safe and efficient operation of the boiler. Adhering to the MTW standard ensures that the boiler tubes can withstand the high pressure and temperature conditions within the boiler.
Sir,Plz reply
The steps involved in wall heater installation typically include: Choosing a suitable location for the heater on the wall. Ensuring proper electrical or gas connections are available. Mounting the heater securely to the wall. Connecting the heater to the power source. Testing the heater to ensure it is working properly. Following manufacturer's instructions for any additional steps or safety precautions.
Overheating of water wall tubes may cause crack. Boiler will damage due to boiler drum level goes down.
To install a wall heater, first choose a suitable location on the wall. Then, follow the manufacturer's instructions for mounting the heater securely. Next, connect the heater to a power source and ensure proper ventilation. Finally, test the heater to ensure it is working correctly. If unsure, consult a professional for installation assistance.
Factors to consider when shopping for a natural gas wall heater is the reputation of the brand, the length of the warranty and the safety features of the heater.
removal of heater hose from engine to fire wall
You clean bricks in a gas wall heater by turning the gas off and scrubbing them with a non flammable cleaner.
could be from your heater if so you can disconnect heater hoses from engine and buy plugs from super cheap auto barn etc to block flow.you will have no heater but a very cheap solution
