Types and Applications of Industrial Boilers: A Complete Guide

What is the industrial boiler?

Industrial Boiler is the equipment to provide steam or hot water. It heat water to a set temperature or pressure producing steam or hot water by combusting fuel, used for heating, drying, powering.

Working principle of industrial boiler

Working principle mainly include burning, heating passing, heating water and vaporization, flue gas emissions, water circulation, water supply system and safe control etc..

Fuel + air → combust → heat → heating surface → water → steam or hot water → use↑

Water supply system

Applications of industrial boiler

Chemical Industry: Used in processes such as ammonia and methanol production, providing high-temperature, high-pressure steam.

Paper industry: Used in processes such as pulp cooking , drying, providing steam or hot water.

Textile industry: Used in processes such as dyeing, drying, providing steam or hot water.

Food industry: Used in processes such as cooking, sterilization, providing steam or hot water.

Pharmaceutical industry: Used in processes such as extraction, distillation, providing steam or hot water.

Power generation industry: used in thermal power generation, producing high-temperature and high-pressure steam to drive steam turbines for electricity generation.

Types of industrial boiler

Classification by use

Power station boiler: it is usually used in conjunction with steam turbines and generations, producing high-temperature and high-pressure steam to drive steam turbines to generate electricity.

Industrial Boiler: Used in industrial production, such as Chemical Industry, Paper industry, Textile industry, providing steam or hot water.

Domestic boiler: Used in providing household hot water, such as heating or bathing.

Classification by fuel

Coal-fired boiler: coal as fuel, high combustion efficiency, but has a certain impact on the environment, need to be equipped dust removal, desulfurization and other environmental protection equipment.

Oil-fired boiler: fueled by oil (such as heavy oil, light oil, etc.), high combustion efficiency, fast startup, but higher operating costs.

Gas-fired boiler: fueled by natural gas, liquefied petroleum gas, etc., clean combustion, good environmental performance, moderate operating costs.

Electric boiler: electric energy as a heat source, through the electric heating element will be converted into heat, quiet operation, no pollution, but the cost of electricity is higher.

Waste heat boiler: utilizing the waste heat generated in the industrial production process (e.g. waste gas, waste liquid, etc.) as the heat source, energy-saving and environmentally friendly.

What are the components of industrial boiler

Combustion equipment: including furnace chamber, burner etc., used for combustion of fuel to provide heat energy.

Heating surface: Such as furnace gallbladder, flue pipe,water pipe, etc.,used to absorb the heat energy generated by the combustion of fuel and heat the water.

Water treating equipment: used to soften water quality, prevent boiler scaling and extend boiler service life.

Safety accessories: such as safety valves, pressure gauges, water level gauges, etc., used to ensure the safe operation of the boiler.

What are the top industrial boiler manufactures?

China

Xizi Clean Energy: Founded in 1955, Xizi Clean Energy is a super-large boiler production base in Chin, and an industry leader in the field of waste heat power generation. Its products cove gas boilers, waste heat boilers, circulating fluidizedbed boilers, biomass boilers, etc., It has presided over (participated in )the formulation of nearly 20 national/ industry standards.

HBC:HBC is the earliest and largest scientific research and manufacturing base of large-scale power station boilers in China, and after more than 60 years of development, it has become a large-scale power generation equipment manufacture with the largest production capacity and the largest scale in China.

Fangkuai Boiler: Fangkuai Boiler Co., Ltd. is a high-tech enterprise specializing in the research, development and manufacturing of clean fuel boilers and clean combustion technology, and holds ISO9001 Quality Management System, OHSAS18001 Occupational Health and Safety Management System and ISO14001 Environmental Management System certificates.

Europe

Viessmann: a German brand, is one of the major manufacturers of industrial boilers in the European market, covering a wide range of boiler types.

Precautions for using industrial boilers

Safe operation

Personnel operating the industrial boiler must hold the appropriate special equipment operator's certificate, such as the G1 industrial boiler stoker's license.

Regularly check the safety valves, pressure gauges, water level gauges and other safety accessories to ensure that they are sensitive and reliable. The safety valves need to be manually discharged and tested regularly, and the pressure gauges need to be calibrated regularly.

Strictly monitor the operating parameters of the boiler, such as temperature, pressure, water level, etc., to ensure that they are within the normal range.Abnormalities found should be dealt with in time, and emergency furnace shutdown measures should be taken when necessary.

Maintenance

Regular inspection and maintenance according to operating situation and use rate boiler, including cleaning inside ash and dirt of boiler, checking and replace elements.

Regularly test the quality of boiler water and steam to ensure that the water quality meets standards. Adjust water treatment measures in a timely manner based on water quality conditions to prevent boiler scaling.

Environmental protection requirements

Ensure that waste gas emissions of boiler meet the criterion of national standard or local standard. Install online monitoring devices for atmospheric pollutants to monitor the emission situation in real time.
