Coal Mill Fuel Pipes

Coal pipe F9 on pulverier B was the only pipe that met the original plant fuel specification guarantee of 70 passing 200 mesh which is far short of the 75 minimum we use. Even so fuel fineness and fuel distribution overall was poor and it resulted in slagging fouling and higherthan

Coal mill fuel pipesPoor pipetopipe fuel balance is a common problem that can occur with any type of pulverier system It is not uncommon for fuel balance between coal pipes to vary by 17730 or more despite having well balanced primary airflow to the fuel pipes Fuel imbalance between burners results in a wide range of Loesche Coal Mills Plant Sies YouTube

Adjusting coal between the coal pipes of a mill using orifices fixed or adjustable is complex because of the twophase flow environment. A restriction in the pipes cross

Obtaining representative samples of coal fineness and fuel distribution is the first step. The best method we have found to do this is by using an isokinetic coal sampler. All fuel lines must be sampled and the fineness sieved from each coal pipe separately. The fuel mass

MECONTROL Coal utilies two independent technologies to measure the mass

The Isolators are closed during maintenance on the mill internals and primary air and pulverised fuel systems. Orifices are often required in pulverised fuel pipes to offset differences in total pipe length and balance pressure between the fuel pipes on each mill.

The direct cost of coal grinding is a function of the wear and tear of the powdered coal mill which in turn is influenced by the expected particle sie spectrum of the coal dust and thus of the

Coal Pipe Balancing Methodology Airflow Sciences Corporation has performed a detailed analysis and design to balance the flow within the coal pipes for numerous plants across North America. The methodology is as follows 1. Utilie the Advanced Coal Flow Measurement ACFM equipment to accurately measure both air flow and coal flow rate in each

Since the first application using an MPS mill to process pulveried coal in Germany in the mid 1960s there have been over 2000 different MPS mill installations operating in coal

Coal is pulveried and dried. Dryer coal is easier to pulverie and less mill power is needed to achieve the same coal fineness. Additionally with less fuel moisture more complete drying of coal can be achieved in the mill. This results in increased mill exit temperature the temperature of the coal and primary air mixture at mill exit

An instrumentation system using multiple electrostatic sensing heads is developed and installed on 510mm bore primary air pipes on the same mill of a 600MW coal

An immediate mill emergency shutdown using the following special procedure a. Maintain the existing fuel feed rate. Changes to the airfuel ratio that increase air flow or decrease coal flow make the fire more dangerous and should be avoided. Thus it is highly recommended to maintain the existing fuel feed rate while the primary air flow is

The measurements and particulate sampling were repeated for eight PC pipes located at two different elevations. Two separate mills referred to as Mill 20 and Mill 40 in this paper supply pulveried coal to the four PC pipes and burners for each elevation.

To achieve optimum and efficient combustion of coal equal quantities of fuel must be delivered to each of the separate burners. These systems utilie a pulverier or mill to grind coal to a desired fineness and subsequently transport the coal to the burners using air as a transport medium .
