What is the difference in Boiler efficiency between CFBC Boiler and PF Boiler while firing powdery coal -50 percent less than 5 mm size?
Cfbc stands for circulating fludised bed combustion where as afbc is for atmospheric fluidise bed combustion afbc bed fluidising velocity is approx 4 m/s and in cfbc boiler fluidising velocity is 9-10 m/s. cfbc having low SOx & NOx comparative with afbc cfbc having higher efficiency up to 98.5 % then afbc boiler,cfbc boiler power consumption is more comparative to afbc.
What is pf fired boiler?
For getting better efficiency from boiler, coal is pulverized in mills (powder form) before entering into boiler along with hot air. This is done in order to control damage to boiler tubes and plates due to high (but cheap) sulphur content in coal. These types of boiler are usually called super critical boiler and works on high pressure (3600psi) and temperature (610 degree C) unlike sub critical boilers. alok bh.
How many liters in one ton of methanol?
One liter of methanol is about 0.8 kg. One tonne of methanol is 1000 kg. Therefore one tonne pf methanol is about 1250 liters
Melting point of Phenol formaldehyde?
Because phenol formaldehyde is a resin it is usually a mixture of chain lengths and cross linking. For this reason, you would not expect it to have a fixed melting point - rather it would usually have either a melting point range or a decomposition temperature (depending on the structure). As an example, the company Polyols and Polymers lists the melting point range of their POLYTONE PF 201 product as 700C-850C while their POLYTONE AP 132 product has a "softening point" of 970C-1100C but no melting point. Bakelite - which is one of the many types of phenol formaldehyde resin - is a thermosetting plastic which has no melting point; it has a decomposition point. As an example, the Bakelite manufactured by Jiacheng-Chem Enterprises Ltd. has a listed decomposition point range of 240~ 280°C. Again, because it is a mixture of polymer sizes and degree of cross linking, it doesn't have just one fixed temperature; it has a range over which the many different molecules will decompose. The temperatures under which phenol formaldehyde will melt, soften, or decompose are also affected by the amount of residual monomers still present in the polymer matrix.

Advantage and disadvantage of synchronous reluctance motor?
they can be used at leading power factor thus can improve PF of the system. They run at constant speed They can be designed with wide air gap thus better mechanical design Their efficiency is higher at low speed and unity PF range,
