DATA ACQUISITION OF STEAM

FLOW TO VARIOUS SECTION OF

HEINZ PVT. LTDAbout Project:-

In this project we are installing a system for the plant in which

they are able to monitoring and recording of the data to

evaluate the efficiencyof eachsection as well as of boiler

generating the steam.

Data includes

Steam flow, steam pressure, steam temperature and steam

consumption in every section of the plant.

These parameters are very important for all kind of plants in

which the plants are using steam for their processes.

Measured values of above parameters are sending to the

control room for the analysis and simultaneously data is

recoded.

Parameters toMonitor and Record

1.Steam flow2.Steam pressure3.Steam temperature

Steam flow:-

In the measurements of the steam flow, we are getting data of

steam flow to sections of the plant and how much amount of

the steam is consumed in the section of the plant.

Steam Pressure:-

Steam pressure we are getting the data of the pressure at

which steam is supplied produced and at which pressure

steam is transferred to the sections of the plant.

Steam Temperature:-

From Steam temperature we are getting the data of the

temperature at which steam is produced and at which pressure

steam is transferred to the sections of the plant.

After measurement of all above parameters we are transferring

the data to the control room in which they are analyzing the

data to the required values and data is simultaneously

recorded.

Steam parameters of the various sections

In this plant we monitoring steam flow at ten different

sections. Various sections are given below:-

TurbineInlet

SprayDryer

Dearater

SprayDryerevaporatorT/CAlfaEvaporator

RollerDryer

TomatoKetchup

VAM

DAIRY &GHEE

These are 9 different section at which we are recording the

steam flow, steam temperature, steam pressure of each section

and then send the data to the control room and recorder.

In this plant they are using two types of steam for their

processes. Two types are:-

1.Super-heated steam.2.Saturated steam

Superheated steam is measured in first two sections and

sections are Turbine inlet and Spray dryer.

And remaining seven sections are using saturated steam for

their processes.

Saturated Steam occurs when steam and water are in

equilibrium. If you have a closed container of water and heatit, above 100C the steam pressure will start to rise, and as thetemperature continues to rise, the pressure will go on rising.What is happening is that steam is being evolved to match thetemperature and the steam conditions are said to be saturatedbecause if the pressure is raised by external means, some ofthe steam will start to condense back to water.

If the steam pressure is held at a lower level than that achievedat saturation, by taking steam off to feed a turbine or other

steam usage, there is effectively an excess temperature forthat pressure, and the steam is said to be superheated. It infact then becomes dry, and behaves as a gas. The amount ofsuperheat can be quantified as so many degrees of superheat(Celsius or Fahrenheit).

Turbine designers want steam to be superheated beforereaching the turbine, to avoid condensation causing bladeerosion, and steam producing boilers in power plants aredesigned to produce superheated steam. In plants where no

turbines are used, only saturated steam is normally generated.

In heating applications, saturated steam is preferable, becauseit has a better energy exchange capacity. Superheated steammust cool down, and become saturated steam, beforecondensing in a heat exchanger. Also, superheated steam is athermal insulator, like air.

MULTIVARIABLE TRANSMITTERWhen evaluating mass flow rates using a primary device

Such as an orifice or nozzle in a differential pressure

Flow meter in order to make fluid density compensations, the

upstream pressure (static pressure) and fluid temperature are

measured in addition to the output of a regular differential

pressure transmitter. In the past in such cases, a differential

pressure transmitter, a pressure transmitter, a temperature

converter and a flow computer were all separately required.

The high performance multivariable transmitter features asingle-crystal silicon resonant sensor and suitable to measureliquid, gas, steam mass flow. This gives outputs a 4 to 20 mA

DC signal corresponding to the measured differential pressure,static pressure, process temperature, or dynamicallycalculated and filly compensated mass flow.

Key Features:-y 1.0% mass flow rate accuracy over 1:10 flow range.y Simultaneous dual output of 4 to 20 mA and pulse signals.y Various function blocks available; 5 ALs, AR, IT, SC and IS

standards. PID as an optional feature.y Software downloads function.

Basic flow calculation mode:-

Flow operation and density compensation are performedconventionally, with the flow factors being input manually.

The operation expression is switched by the fluid type andunit setting.

Density compensation by phase

Gas: compensation as ideal gas by temperature and pressure.

Liquid: Compensation by Temperature.
