  • What are the constructions of water wall tubes? 2019-11-08
    Evaporation phase occurs in water wall tubes. Evaporation is the process to convert water into steam. Therefore water wall tubes should be designed and constructed to provide high heat absorption, minimum excess air level and highest boiler efficiency. Construction of water wall tubes should be also constructed to prevent air leakage into steam boiler, eliminate amount of heat losses and permit high heat release and combustion rate in the furnace. Construction of water wall tubes must provide high quality of the supporting component such as tubes, casing, refractory, lagging, tile, fin, and so on. Best construction will reduce heat loss and maintenance. Construction of water wall tubes can be classified into four types such as:
  • Saturated Vs superheat steam conditions 2019-10-18
    In a boiler, energy from the fuel is transferred to liquid water in order to create steam. Once the water is heated to boiling point, it is vaporized and turned into saturated steam. When saturated steam is heated above boiling point, dry steam is created and all traces of moisture are erased. This is called superheated steam.
  • How do industrial boilers work? 2019-10-04
    All boilers, whether hot water or steam, depend on fuel to run. The heating process is initiated when the burner heats or evaporates the water inside it, which is ultimately transported via pipe systems. Hot water boilers rely on pumps to move the heat through the system, while steam boilers are transported with the pressure generated in the heating process. Eventually, cooled water or condensed steam is returned back through the pipes to the boiler system so that it can be heated once again. While the boiler is generating energy in the form of heat, flue gases, a byproduct of this process, are removed through a chimney system - which is why regulating the emissions of industrial boilers is taken very seriously.
  • Firetube vs watertube boilers: a comparison 2019-09-18
    There are a number of considerations to factor when determining the best boiler for your steam generation needs like operating pressure, steam pounds/hour output, demand fluctuation, general application requirments and total cost of ownership, etc. Two primary boiler types, the firetube boiler and the watertube boiler, are essentially opposite in design. The firetube boiler passes combustion gas inside a series of tubes surrounded by water in a vessel to produce steam, while a watertube instead sends water through a series of tubes surrounded by combustion gas used to transfer heat energy and produce steam.
  • What are NOx emissions standards? 2019-09-06
    Nitrogen Oxides, commonly referred to as NOx, is a family of poisonous gases. These gases are best known for their role in air pollution, leading to occurrences of acid rain, smog, and the deterioration of the ozone layer.In short, NOx is harmful to the atmosphere and the environment and needs to be limited as much as possible.The problem is that NOx is quite common. It's created as a result of fuel burning at high temperatures. Cars, trucks, boats, and other kinds of vehicles emit NOx almost co...
  • Why Does My Business Need a Low NOx Boiler? 2019-08-16
    Today's businesses, regardless of industry, can always do more to improve their sustainability and limit the negative impact their actions have on the environment. There are a number of ways to do this, but one of the best is to use a boiler that's designed to limit the emissions of NOx — one of the most harmful greenhouse gases humans emit into the atmosphere. Aside from being good for the environment, a low NOx boiler can also be good for business.
  • How to calculate the gas consumption in a boiler? 2019-07-19
    The boiler gas consumption calculation need the following parameters: gas calorific value and boiler thermal efficiency. Theoretically, the gas consumption of boiler = boiler thermal capacity ÷ (calorific value of gas x boiler thermal efficiency ) Take the 1 tph steam boiler as an example: = 600,000 cal / (8500Kcal * 0.98) =72m3/h, the 1 tph boiler's gas consumption per hour is about 72 cubic meters.
  • In what sectors are industrial steam boilers used? 2019-07-12
    The main sectors in which industrial steam boilers are used are: Food, in industrial bakeries or baby food (as an example) Textile, in rotary dryers Chemical, for reactors or storage Pharmaceutical, for the manufacture of medicines Cosmetics, for the production of perfumes and creams Stationery and printing, in drying tunnels The cement industry, for the manufacture of cement parts Oil, for the storage and distribution of heavy oils Wood, involved in the process of melanin production Hospitals and hotels, especially in the laundry and kitchen areas Automotive and surface treatment, for the final metal finishing.
