What is water wall in boiler?
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.
What is Boiler feed pump?
Function - It adds the pressure to the feed water before it entyers into boiler feed pump suction Advantage - Ensures high margin NPSH A for boiler feed pump spinning at high rpm (5250Rpm) Drive for booster - Normally @1450 rpm Type of impeller- Mostly preferred Double suction
What ar the fluid zed bed boiler ant it's types?
A fluidized bed boiler is a type of industrial boiler that uses a fluidized bed of solid particles, typically sand or ash, to combust fuel efficiently at lower temperatures. The process involves blowing air through the bed, causing the solids to behave like a fluid, which enhances heat transfer and combustion efficiency. There are two main types of fluidized bed boilers: bubbling fluidized bed (BFB) boilers, where the bed bubbles up due to air flow, and circulating fluidized bed (CFB) boilers, where particles are continuously circulated through the system for better combustion and heat transfer. Both types are known for their ability to burn a wide variety of fuels, including biomass and waste materials, with reduced emissions.
What can blast furnace waste slag be used for?
its used a fuel , but has less calorific value as the carbon monoxide percentage is less which is the main combustible gas in the b.f gas. its used in heating the blast of hot air in the blast furnance itself and also can be used in rolling mill, sinter plant, and many more where you need heating

What is acid refractories?
Acid refractories are a type of ceramic material that can withstand high temperatures and harsh chemical environments with a high resistance to acidic corrosion. They are commonly used in industries like steel production, petrochemicals, and glass manufacturing where acidic conditions are prevalent. Acid refractories are typically made from silica and alumina as main components.
Boiler drum which chemicals are using?
chemical is used in sub critical boiler that is tri sodium phosphate added in durm. The main purpose is raise in pH value , salt is converted in to sludge form
What is Auxiliary Boiler?
An auxiliary boiler is a secondary boiler used to support the main boiler in a steam power plant or marine vessel. It is often used when the main boiler is unable to meet the steam demands, providing additional steam capacity. Auxiliary boilers can also be used for heating purposes during maintenance or downtime of the main boiler.

Why hook up two thermostats to one gas furnace?
My "furnace" is a boiler with one zone circulating the entire house. I have a wood burning fire place on the main floor. The thermostat is also on the main floor. When I burn the fire place, the main floor heats up and the lower floor gets colder than crap. I want to install a second thermostat on the lower floor to keep the boiler @ 70 degrees....to keep that lower floor at 70 degrees....inspite the fact that the upper floor, with the fireplace burning, raises the temp on the main floor up to as much as 80 degrees! Yeah, yeah, why burn the fire place and the boiler at the same time. Answer, to keep the lower floor warm! Can't run duct work from the main floor fire place to the lower floor in a finished house!
What are the 2 main types of boilers?
Fire tube and water tube. Steam Boiler and Water Boiler.

What is the difference between ID and FD fan?
The main difference between an ID (Induced Draft) fan and a FD (Forced Draft) fan lies in their placement in a system. An ID fan is located after the furnace or boiler and helps to draw waste gases out of the system, while an FD fan is positioned before the furnace or boiler to supply fresh air into the system for combustion. ID fans create negative pressure, while FD fans create positive pressure within the system.
