How can incomplete combustion occur in a gas boiler?
Incomplete combustion inevitably occurs when fuel is burned with insufficient oxygen. In the case of gas appliances this can occur if the system for mixing fuel and air is incorrectly set or if the flow of air to the appliance is inadequate.
Where does combustion take place in a coal-burning power plant?
We can probably say the firebox of the boiler is where combustion takes place in a coal-fired power plant.A coal pulverizer feeds the coal into the firebox (burner or combustion chamber) along with forced air. The air-coal mix is ignited in the hot environment, and the heat rises to the coils in the upper part of the boiler. In the bottom of the combustion area we find the ash or slag collector.
Is the internal combustion engine's fuel burns outside the engine in chambers called cylinders?
Internal combustion refers to an engine were the combustion process takes place inside the engine. The cylinders in question are an internal portion of the cylinder block which houses the crankshaft, connecting rods and the pistons which move up and down in the cylinder drawing in the air fuel mixture, are forced down by the combustion process, and push the spend fuel charge out of the cylinder at the end of the cycle. An example of an external combustion engine would be a steam engine where the combustion takes place in a boiler external to the engine and the steam generated by the boiler is used to motivate the engine.
What are the three requirements of combustion?
When coal is burned in the boiler of a power plant, it is not just set alight like the coal in a domestic fireplace. It has to burn fast¾ for power is the energy converted per second, and it has to burn completely¾for efficiency is a measure of how much energy is usefully harnessed rather than lost. The efficient combustion of coal needs the "three T's"¾temperature high enough to ignite the fuel, turbulence vigorous enough for the fuel constituents to be exposed to the oxygen of the air, and time long enough to assure complete combustion. The three requirements are best met by pulverized coal, which is forced into the furnace by an air stream under high pressure and is ignited as it enters through a nozzle. Pulverized coal was introduced in the early 1920's and represented a major advance over the previous stoker firing.
What is the PH value in boiler feed water?
the pH value in boiler feed water is 9.2
What is boiler combustion efficiency?
boiler efficiency is how much water is converting to steam.
Is a boiler an internal combustion engine?
No because there isn't any combustion happing inside the boiler the water is heated by an external flame and boils the water.
What is the world's largest internal combustion engine?
boiler
What is afbc boiler?
Atmospheric Fluidized Bed Combustion Boiler (AFBC boiler) is a type of operational boiler. In a AFBC boiler a little more fluidized bed combustor is added than a conventional shell boiler.
How can incomplete combustion occur in a gas boiler?
Incomplete combustion inevitably occurs when fuel is burned with insufficient oxygen. In the case of gas appliances this can occur if the system for mixing fuel and air is incorrectly set or if the flow of air to the appliance is inadequate.
What is an atmospheric boiler?
ATMOSPHERIC BOILERa boiler on which combustion air/flue gases are drawn through the boiler without a fan.(Taken directly from the Crown Boiler Co. web-site.)
What is the most important difference between and internal combustion engine and an external combustion engine?
in internal combustion engine combustion happens internally in cylinder and in external combustion engine combustion happens externally in boiler
What is the most important difference between an international combustion engine and an external combustion engine?
in internal combustion engine combustion happens internally in cylinder and in external combustion engine combustion happens externally in boiler
Cfbc boiler full form?
Circulating fluidised bed combustion
What is afbc boiler full form?
atmospheric fluidized bed combustion
What is air-standard cycle?
air standard cycle is theoretical cycle and actual cycle is .................
What constitutes the heating surface of steam boiler?
The heating surface of a boiler is all the surfaces that have boiler water on one side and hot gases of combustion on the other. The surface in contact with the water is the surface that is measured.
