What is a boiler for Textile mills ?

List of  boiler machine for Textile Mills and Apparel Industry is  closed vessel in which water or other liquid is heated, steam or vapor is generated, steam is superheated, or any combination thereof, under pressure or vacuum, for use external to itself, by the direct application of energy from the combustion of fuels, from electricity or nuclear energy. These are fired units for heating or vaporizing liquids other than water where these units are separate from processing systems and are complete within themselves. The definition includes water heaters that exceed 200,000 Btu/hr heat input, 200 degrees Fahrenheit at the outlet, or 120 gallons nominal water containing heating capacity

Advantage of Different Types of Boiler:

• Energy Saver of boiler can improve boiler thermal efficiency
• Lower dust emission and SO2, NOx emission
• Dust emission concentration < 45mg/m³
• SO2 & NOx emission concentration < 30mg/m³
• Boiler should have fuel combustion, Inverter control that can achieve automatic adjustment
• Automatic pressure control, temperature control & feed water control
• It is anti-corrosion & anti-rust

Working Procedure of Boiler:

• Build a standard boiler house for textile factory
• Prepare piping as boiler technical information,
• Preparing electricity based on requirement,
• Installed boiler as manual,
• Commissioning boiler as manual,

Maintenance Cost for Gas Types of Boiler & Per Kg Steam Cost:

• Big Boiler capacity = 7,500 kg/hr
• Small Boiler capacity = 5,000 kg/hr
• Boiler Total capacity = (7,500+5,000) kg/hr

= 12,500 kg/hr

• Life Time = 15 Years

= (15×12) Months

= 180 Months.

Materials/Spare Parts Rate For Gas Boiler:

Find Out Gas Bill For Gas Boiler:

• For Small Boiler (5000 kg/hr) We Use = 3,368 m3 gas/Day (Average)
• For Big Boiler (7500 kg/hr) We use = 6,150 m3 gas/Day (Average)
• Per Day Total gas use for both boiler = (3,368+6,150) m3

= 9,518 m3 (Average)

• Per Month Total gas use for Both boiler = (9,518×28) m3

= 2, 66,504 m3 (Average)

• 01 m3 gas cost = 5.25 Tk.

2, 66,504 m3 gas cost = (2, 66,504×5.25) Tk.

= 13, 99,146 Tk.

• Per Month Gas Bill for Boiler = 13, 99,146 Tk.

Find Out Electricity Bill For Gas Boiler

• Big Boiler KW = 17.32 KWH
• Small Boiler KW = 15.24 KWH
• Total KWH = (17.32+15.24) KWH

= 32.56 KWH

• Per Day Used For Boiler = (32.56×24) KW

= 782 KW

• Per Month Used For Boiler = (782×28) KW

= 21,896 KW

• Per KWH Electricity Cost = 2.78 Tk.
• Total Electricity Cost per Month for Boiler = (21,896×2.78) Tk.

= 60,871 Tk.

Total Cost Per Month For Boiler:

• Total Cost per Month for Boiler = 15, 58,562 Tk.
• Total Cost per Year for Boiler = (15, 58,562×12) Tk.

= 1, 87, 02,744 Tk.

• Total Cost per Day for Boiler = (2, 08, 15,008÷365) Tk.

= 51,240 Tk.

• Total Cost per Hour for Boiler = (51,240÷24) Tk.

= 2,135 Tk.
