There are several ways to estimate the thermal efficiency of gas-fired boilers:
1. Direct method: This method involves measuring the amount of fuel consumed and the amount of heat produced by the boiler. By comparing these two values, it is possible to calculate the thermal efficiency of the boiler.
2. Indirect method: The indirect method involves measuring various parameters such as flue gas temperature, ambient air temperature, and fuel consumption, and then calculating the t...
The main working principle of industry is a kind of heating equipment which uses the heat energy released after fuel combustion or the waste heat in industrial production to transfer to the medium in the container, so that the medium can reach the required temperature, and then it can be transported to the heating process for heat exchange. According to different media, boilers can be divided into many types.
Types of boiler heating medium
1. Steam, steam boiler and superheated steam b...
In this question, what is the tonnage of a 6 million kcal boiler? Tonnage and 10,000 kcal are the expressions of boiler heat supply or boiler capacity. However, the relationship between different representations is unclear to many users.
Boiler capacity unit
Before the announcement of the equivalent tonnage of 6 million kcal boiler, the common boiler heat supply units in China were summarized:
Kcal/hour (Kcal/h) is a metric unit, which means the heat that the boiler can provide per ...
Prepare relevant technical data, including technical data of boiler manufacture and installation, boiler use registration data, boiler operation records, water quality test records, repair and modification records, accident records and previous inspection reports;
The term Thermal Fluid does not refer to a specific fluid, there are many. There are also many companies that produce a variety of Thermal Fluids.
The most common Thermal Fluids are either Mineral Oil based or Synthetic Oils. The various manufacturers typically produce a series of fluids that each has a recommended operating temperature range. Close consideration should be given to this operating range in selecting a fluid.
There are other considerations as well, consult with f...
From wood burning to pellet-firing biomass, alternative fuel boilers and solid fuel fired boilers offer environmentally friendly energy options and cost efficiencies. With the push to become less reliant on fossil fuels, alternative fuel boilers provide a way for plant managers to save money on fuel sources as well as meet tightening emission regulation standards.
First of all, we should consider the thermal insulation effect. The main function of a gas-fired boiler is to provide heat energy. Good surface packaging material can avoid heat loss and save the fuel. It is suggested to choose glass wool which has a good insulation effect.
Secondly, we should consider the boiler appearance. It is best to choose a white color plate package when buying a gas-fired boiler, which not only has a beautiful appearance but also has a good insulation effect.
Finally, we should consider the boiler size. Wrong boiler size will cause some unnecessary troubles.
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:
