A steam boiler is a device that converts fuel into high-temperature steam, which is widely used in industrial, commercial, and domestic fields. The model parameters of the steam boiler are of great significance for the selection and use of the boiler. The main model parameters of steam boilers will be described in detail below.
First, the model. The model number of a steam boiler is usually composed of numbers and letters, which contains information such as the design pressure of the boiler, the rated evaporation capacity, the rated steam pressure, the type of fuel, and the scope of application. For example, the model number is DZL6-10 130 70-q steam boiler, where dzl represents a single-barrel longitudinal chain grate steam boiler, 6 indicates a rated evaporation capacity of 6t h, 10 means that the rated working pressure is 10MPa, 130 means that the superheated steam temperature is 130, 70 means that the temperature of saturated steam is 70, and Q means that the fuel is gas.
Second, the main parameters.
1.Rated evaporation.
The rated evaporation capacity is the amount of steam produced per hour by the steam boiler under normal working conditions, and the unit is t h. The magnitude of evaporation determines the size of the boiler and the required fuel consumption. When choosing a steam boiler, it is necessary to determine the appropriate evaporation capacity according to the actual needs and use.
2.Rated working pressure.
The rated working pressure refers to the maximum pressure that the steam boiler can withstand under normal working conditions, and the unit is MPa. The magnitude of the working pressure determines the quality and temperature of the steam. When choosing a steam boiler, it is necessary to determine the appropriate pressure according to the actual needs and use.
3.Thermal efficiency.
Thermal efficiency is the ratio of the heat generated by a steam boiler to the fuel consumed under normal operating conditions, and is measured in %. The level of thermal efficiency reflects the energy efficiency of the boiler. In general, the higher the thermal efficiency, the more energy can be used, which can reduce energy costs. Therefore, when choosing a steam boiler, you need to choose a boiler with high thermal efficiency.
4.Applicable fuel type.
The type of fuel that the steam boiler is suitable for is also one of the important parameters. Different fuel types affect the performance, efficiency and safety of boilers. Common types of fuels include coal, fuel oil, gas, etc. When choosing a steam boiler, it is necessary to determine the appropriate type of fuel according to the actual demand and fuel situation.
5.Safety protection device.
The safety of a steam boiler is very important, so it is necessary to choose a boiler with safety protection devices. The safety protection device includes overpressure alarm, low water level alarm, flameout protection, etc., which can alarm and cut off the power supply in time under abnormal conditions to ensure the safety of equipment and personnel. When choosing a steam boiler, it is necessary to pay attention to whether it has a complete safety protection device.
To sum up, choosing the right steam boiler requires determining the appropriate model and parameters according to the actual needs and uses. Knowing the model parameters of a steam boiler helps to select and use the boiler correctly, improve energy efficiency, and ensure the safety of equipment and personnel.
