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
