Explanation of the natural gas consumption and protection device of a 4-ton gas


The gas boiler is quickly installed and shipped from the factory, with a compact structure and a small footprint. The boiler fuel uses pipeline gas or bottled gas, and there is no need to set up a special fuel storage area. It occupies a small area and is simple and convenient to operate. Users use gas boilers to be energy-efficient enough to reduce operating costs and maximize production benefits. How much natural gas does a 4-ton gas boiler consume in one day? What are the safety interlock protection devices for steam boilers?


1. The natural gas consumption of a 4-ton gas boiler in one day


The gas consumption calculation formula of the gas boiler is: gas boiler gas consumption (per hour) = gas boiler power * time / fuel calorific value / thermal efficiency.


The power of a 4-ton gas boiler is 2.8MW, the calorific value of the fuel is 35.53MJ/Nm3, and it is assumed that the thermal efficiency of the gas boiler is 88%. Then, the gas consumption of a 4-ton gas boiler per hour = 2.8MW*3600s/35.53MJ/Nm3/88%=320m3/h. Running 24 hours a day, natural gas consumption = 320*24 = 7680 cubic meters. The gas boiler configuration should be reasonable to ensure the boiler operating conditions and production benefits.


2. Steam boiler safety interlock protection device


1. Steam boilers shall be equipped with high and low water level alarms (high and low water level alarm signals shall be distinguishable). Boilers with rated evaporation capacity ≥2t/h shall also be equipped with low water level interlock protection devices, which shall be activated at the lowest safe water level at the latest;


2. Boilers with rated evaporation capacity ≥6t/h shall be equipped with overpressure alarm and interlock protection devices, and the overpressure interlock protection device action setting value shall be lower than the lower set pressure value of the safety valve;


3. The superheater and reheater of the boiler shall adopt corresponding protection measures to prevent metal wall overheating according to the unit operation mode, automatic control conditions, superheater and reheater design structure; the reheat steam system shall be equipped with an emergency water spray device and be automatically put into use;


4. For boilers placed in multi-story or high-rise buildings, each boiler shall be equipped with an overpressure (overtemperature) interlock protection device and a low water level interlock protection device. The advantages of steam boilers are obvious, and they will not be listed one by one. If you need, you can consult our company to send detailed information.
