15t coal-fired steam boiler refers to the boiler equipment which takes all kinds of coal as fuel, generates 15t steam per hour under the rated working pressure after the heat of coal is converted. When purchasing a 15t coal-fired steam boiler, users need to pay attention to the analysis of technical parameters, which is not only related to the purchase price, but also determines whether the daily heat demand can be met in the later period. Here, ZOZEN Boiler focuses on introducing the common 15t...
The thermal oil heater, also called organic heat carrier boiler, provides heat energy for production by heating the heat medium oil. It can realize the high-temperature and low-pressure heating without constant water supply. What are the characteristics of the thermal oil heater?
Coal-fired boilers refer to boilers that use various kinds of coals as fuel and convert the heat value of coals to steam or hot water.
Some specific parameters should be provided to calculate the theoretical coal consumption of a set of 20 tph coal-fired boiler. If the rated steam pressure is 1 MPa, the heat value of coal is 7000 kcal / kg, the boiler inlet water temperature is 20 ° C, and the boiler thermal efficiency is 80%, the daily coal consumption is 50-56 tons.
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:
