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...
a) Boiler hot water system design should meet the requirements of Code for design of boiler plant GB50041.
b) Steam collecting device should be installed in the highest position of hot water system and the position where is easy to collect steam. Reliable constant pressure measures and circulating water expansion device should also be set to ensure that pressure in system is not lower than the corresponding saturation pressure of outlet water temperature plus 20 °C so as to avoid boiler wat...
Boiler is the important energy equipment in industrial production, and it has a high application frequency in textile and garment factories. Faced with numerous boiler products and brands in the market, which brand of boiler is good in the garment factory has become a topic that users are particularly concerned about. Here, ZOZEN Boiler will take you to learn the usage and brand selection of boilers in garment factories.
The usage of the boiler in garment factory
Before introducing whi...
Due to the limitation of electric power, natural gas supply and gas pipeline, it is impossible to change all coal-fired boilers into electric or gas-fired boilers. At this time, Shandong biomass boiler with biomass energy as fuel has attracted the attention of many enterprises.
As we all know, biomass energy is an important renewable energy source, which is green, low-carbon, clean and renewable. However, due to the more complex fuel characteristics of biomass fuel, furnace arch collaps...
Evaporation tube bundle and water cooling tube panel are two important heating surfaces of the boiler, which are all arranged inside the boiler, so it is not easy to see them intuitively.
Boiler evaporation tube bundle
Evaporation tube bundle mainly absorbs convection heat transfer in small and medium-sized boilers. Generally, it is a bundle of dense staggered piping systems consisting of ascending pipes and descending pipes that connect the upper and lower drums. The heat load of the ...
Gas and oil steam boiler refers to an industrial boiler that uses oil and gas fuels to heat water to a certain parameter and produce high-temperature steam. The water is heated in the drum and becomes steam, and the fire gives off heat in the furnace. Gas and oil steam boiler is a kind of special equipment, and its design, processing, manufacturing, installation and use must be supervised by the technical supervision department. When users buy steam boilers, the first concern is the quotation of...
Low-carbon condensing gas boiler takes clean energy natural gas as fuel, and uses high-efficiency flue gas condensation waste heat recovery device to absorb sensible heat and latent heat released by steam condensation in the tail of the boiler, so as to achieve the purpose of improving boiler thermal efficiency and saving energy, thereby reducing carbon emissions.
Low-carbon gas-fired boiler recovers the energy from the hot flue gas (generally around 140℃) emitted by the boiler through ...
The fuel cost of 10 tph electric boiler: 7,100 kilowatt-hour is multiplied by the local industrial electricity unit price which is nearly 1 RMB, so we can get 1 RMB/kWh and the fuel cost is about 7,100 RMB per hour.
