  • What is the classification of common boiler water? 2022-01-21
    Raw water: refers to water that has not been disinfected and filtered, such as river water, stream water, well water, reservoir water, etc. Feed water: refers to the chemical water delivered from deaerator to boiler by feed pump. Make-up water: Make-up water for boiler is to make up the lost part or externally supplied part after completing a steam-water cycle, so that the boiler can always operate at a safe water level. Recycling condensing water: When the heat energy of steam or hot water i...
  • What is the function of boiler drum? 2022-01-21
    The boiler drum is connected with downcomer and water wall to form a natural circulation loop. At the same time, the boiler drum receives the feed water from the economizer and delivers saturated steam to the superheater. Therefore, the boiler drum is the connecting hub of the three processes of heating, evaporation and overheating in the boiler.
  • What's the price of an 80-ton gas-fired steam boiler? 2022-01-21
    When choosing the 80-ton gas-fired steam boiler, the price determines the customer's upfront investment cost, so it is as important as the quality. However, the price is not determined by a single factor, it is related to many aspects, the price of 80-ton gas-fired steam boiler will be different with different choices. Let’s talk about what are the main factors that affect the 80-ton gas-fired steam boiler?
  • What are the conditions and preparations for low-pressure boiler furnace drying? 2022-01-14
    (1) The boiler and all auxiliary equipment are installed, and all tests such as ball passing test, hydrostatic test and air tightness test are qualified. (2) All rotating devices, feed water pumps, condensate pumps, salt solution pumps, blowers and induced draft fans for coal conveying, combustion and ash removal are qualified for trial operation. (3) The fuel and water supply are guaranteed, the steam, water and flue gas piping system are normal, and the connection unrelated to the boiler to ...
  • What are the water quality requirements of medium pressure steam boiler feed water? 2022-01-07
    The main water quality indexes of medium and high pressure steam boiler water are hardness, dissolved oxygen, iron, copper, sodium and silicon dioxide.
  • What are the characteristics of water softening equipment of medium and high pressure steam boiler? 2022-01-07
    Among the commonly used steam boilers, those under the pressure of 3.825 MPa are called medium pressure steam boilers, and those under the pressure from 9.8 MPa to 13 MPa are called high pressure steam boilers. Different boiler pressures have different requirements for water quality. Generally, medium and low pressure steam boilers need to supplement softened water, and softened alkali-free water, while high pressure boilers need desalted water. The different water qualities require different corresponding treatment equipment.
  • What is the higher heating value and lower heating value of fuel? 2021-12-31
    The higher heating value of natural gas refers to the total heat released when a specified amount of natural gas is completely burned, including the latent heat of vaporization released by the condensation of water vapor in flue gas into water.   The lower heating value of natural gas refers to the heat released when a specified amount of gas is completely burned, the temperature of combustion products is the same as the initial temperature of natural gas, and the generated steam remains ...
  • Why do atmospheric gas-fired hot water boilers have to use on-off valves? 2021-12-31
    There are many valves commonly used in atmospheric gas-fired boilers, including gate valves and stop valves of main steam valves, water supply valves, check valves, exhaust valves, etc.   When the water pump is turned on, the pressure signal is transmitted to the on-off valve of the atmospheric gas-fired boiler through the pressure pipe, the valve is opened, and the water circulation is carried out. When the water pump stops, the pressure drops, and the on-off valve is closed slowly to av...
