  • What are the heating methods of industrial boilers? 2024-06-07
    Industrial boilers are important thermal energy supply equipment in the national economy. Electric power, machinery, metallurgy, chemical industry, textile, paper, food and other industries, as well as industrial and civil heating all require boilers to supply a large amount of thermal energy. Here, ZOZEN Boiler summarizes the heating methods and principles of industrial boilers, hoping to help everyone. Generally speaking, the heating methods of industrial boilers mainly include conduction, co...
  • What applications do steam boilers have in the pharmaceutical industry? 2024-04-26
    The pharmaceutical sector is an area that requires the highest quality steam for its processes, known as clean steam, instead of other industrial steams. Some processes in this sector even need the highest level of quality - pure steam, which involves even stricter steam purity requirements for use in the sterilization of raw materials and pharmaceutical products at high temperatures.
  • What are the precautions for the explosion-proof door of the industrial boiler? 2024-03-29
    During the ignition and operation of the chamber combustion boiler fueled by pulverized coal, oil or combustible gas, improper operation can cause the deflagration or secondary combustion in the furnace or flue gas duct, which can further cause the increased pressure in the furnace. When the pressure reaches a certain value, the explosion-proof door is necessary to open automatically to protect the furnace wall of the boiler.
  • How to select a set of gas-fired boiler for heating supply of an area of 200,000 m2 2024-03-22
    Selecting a gas-fired boiler for heating a 200,000 m^2 area involves several considerations to ensure efficient, reliable, and cost-effective operation. Here’s a structured approach: 1. Determine Heating Demand First, calculate the total heating demand of the 200,000 m^2 area. Heating demand varies based on climate, building insulation, usage, and local standards. A rough estimate for moderate climates is 100 W/m^2, but this can vary. 2. Choose Boiler Type Decide on the boiler type. Fo...
  • Do biomass boilers produce any smoke or other emissions? 2024-03-22
    A well designed and operated biomass boiler burning fuel within the specification of the boiler should not produce any smoke, but black smoke may be produced if the fuel is too wet for the boiler. All biomass boilers produce some oxides of nitrogen (NOx), particularly nitrogen dioxide (NO2). While NOx emissions from gas boilers have been reduced significantly in recent years through the use of low NOx burners which burn at a temperature slightly below that at which NOx forms, the nature of biomass combustion, and the need to ensure the complete combustion of wood gases, means that combustion takes place at a temperature where atmospheric oxygen and nitrogen can chemically combine. The better the quality of the combustion control system on a biomass boiler, the lower the NOx emissions will be. In general, biomass boilers produce less NOx than oil boilers. Biomass boilers do not produce any oxides of sulphur (SOx).
  • What is the function of the slag produced by a biomass boiler? 2024-03-15
    The slag produced by a biomass-fired boiler can be reused to avoid energy waste and environmental pollution. There are many ways to reuse the slag. For example, the slag can be used to improve soil and improve soil performance. If it contains potassium carbonate and organic matter, it can also be used to produce compound fertilizers. In addition, the slag is a kind of plant ash, it is also a good thermal insulation material for steelmaking.
  • What are the operating process and precation of drying for coal-fired boiler? 2024-02-23
    In the whole drying process, we should pay attention to gradually increasing the temperature instead of burning by raging fire; regularly checking boiler's water level and keeping it within the normal range; keeping the flame balanced in the furnace. In addition, we also should properly open the drainage valve and maintain the water level, regularly record the flue gas temperature to control the rise of temperature and high temperature and keep the temperature within the normal range. In general, under these conditions, boiler’s drying quality can be ensured.
  • What is the exhaust gas concentration of the biomass-fired boiler and how to deal with it in a more eco-friendly way? 2024-02-23
    The pollution discharge of the biomass-fired boiler is less than the coal-fired boiler. It is also necessary to deal with the exhaust gas of the biomass-fired boiler to meet the national standards before boiler ignition and operation.
