Presentation on LANCASHIRE BIOLER BY SHAKEEL AHMED.pptxbaghbana bajoi
what is Lancashire boiler?
Lancashire boiler is a horizontal drum axis, natural circulation, natural draft, two-tubular, low pressure, stationary, fire tube boiler with furnace located internally. Its main purpose is to create steam and then this steam is used to drive steam turbines for power generation. It has high thermal efficiency and it is about 80 to 90 percent. It is mostly used in locomotive engines and marines etc
=> The Lancashire Boiler works on the principle of Heat Exchanger. A Heat Exchanger is a device that is used for the transfer of heat between two or more fluids.
=> At first, water is fed uniformly to the boiler shell using the feed pump.
Before entering into the boiler, the water is preheated using the economizer which gets heat from the flue gases. This economizer increases the efficiency of the boiler.
After that, solid fuel is entered from the fire door and burnt on the grate which is present at the starting if each fire tube.
As the solid fuel is burnt, flue gases start traveling in the fire tube.
There is a small brick arc which stops ashes and burnt coal to enter into the fire tube.
As the flue gases pass through the fire tubes, these fire tubes start getting heated and the heat is transferred to the water which is surrounding the fire tube
As the heat is transferred to the water, the water starts to get converting into steam and the steam generated is transferred to the required place using the stop valve.
=> Before reaching the stop valve the steam crosses the superheater which superheats the steam before delivering it to the required place.
After passing through the firetube, the flue gases go to the bottom channel which is created in the brickwork and then the flue gases pass through the side channel.
As the flue gases pass through the channels in the brickwork, these flue gases come in contact with the boiler shell and the boiler shell gets heated and this heat is transferred to the water inside the boiler shell and the efficiency of boiler is increased.
channel and transfer heat to the superheater before passing through the chimney.
The flue gases after passing through side channels transfer the heat to the superheater and then escapes to the environment through the chimney.
=>what is Damper in boiler?
A damper, which is used to control the draft inside a boiler. ... When hot air from the boiler rises up the stack, it must be replaced by cooler air surrounding the boiler. This cooler air will push the warmer air up the stack, causing flow.
//Accessories of Lancashire boiler//
=> Economizer:
An economizer is a mechanical device that is used as a heat exchanger in the steam power plant.
It is used to pre-heat the fluid or water by taking the residual heat from the combustion products( flue gases).
It is installed to increase the efficiency of the boiler.

Harnessing WebAssembly for Real-time Stateless Streaming PipelinesChristina Lin
Traditionally, dealing with real-time data pipelines has involved significant overhead, even for straightforward tasks like data transformation or masking. However, in this talk, we’ll venture into the dynamic realm of WebAssembly (WASM) and discover how it can revolutionize the creation of stateless streaming pipelines within a Kafka (Redpanda) broker. These pipelines are adept at managing low-latency, high-data-volume scenarios.
NUMERICAL SIMULATIONS OF HEAT AND MASS TRANSFER IN CONDENSING HEAT EXCHANGERS...ssuser7dcef0
Power plants release a large amount of water vapor into the
atmosphere through the stack. The flue gas can be a potential
source for obtaining much needed cooling water for a power
plant. If a power plant could recover and reuse a portion of this
moisture, it could reduce its total cooling water intake
requirement. One of the most practical way to recover water
from flue gas is to use a condensing heat exchanger. The power
plant could also recover latent heat due to condensation as well
as sensible heat due to lowering the flue gas exit temperature.
Additionally, harmful acids released from the stack can be
reduced in a condensing heat exchanger by acid condensation. reduced in a condensing heat exchanger by acid condensation.
Condensation of vapors in flue gas is a complicated
phenomenon since heat and mass transfer of water vapor and
various acids simultaneously occur in the presence of noncondensable
gases such as nitrogen and oxygen. Design of a
condenser depends on the knowledge and understanding of the
heat and mass transfer processes. A computer program for
numerical simulations of water (H2O) and sulfuric acid (H2SO4)
condensation in a flue gas condensing heat exchanger was
developed using MATLAB. Governing equations based on
mass and energy balances for the system were derived to
predict variables such as flue gas exit temperature, cooling
water outlet temperature, mole fraction and condensation rates
of water and sulfuric acid vapors. The equations were solved
using an iterative solution technique with calculations of heat
and mass transfer coefficients and physical properties.
1. Boilers
Presented by: Lisa Chang
Objective: To describe and explain the boilers’
functions and the two main types of boilers.
2. What is a boiler?
A water containing vessel in which water is
heated under pressure
Transfer heat from a fuel source (oil, gas, coal)
into steam
The steam or hot fluid circulates out of the
boiler for use in various process or heating
appliances.
3. How does a boiler work?
Closed system: when 100% of the steam
produced is returned to be reused.
Examples of closed systems are close steam
heating, hot water heating, and “one-pipe”
systems.
Open system: a system that does not return the
condensate.
4.
5. Fire Tube Boilers
• The combustion gases pass inside boiler
tubes, and heat is transferred to water on the
shell side.
6. Water Tube Boilers
• Boiler water passes
through the tubes
while the exhaust
gases remain in the
shell side, passing
over the tube
surfaces.
7. Conclusion
Boilers are classified into fire tube or water
tube boilers depending on whether the heat
source is inside or outside the tubes.
The goal in both cases is to maximize the heat
transfer between the water and the hot gases
heating it.
