1. What is a coal-fired chain grate boiler?A coal-fired chain grate boiler is a type of industrial boiler that uses a chain grate as its combustion equipment. The fuel enters the chain grate through the coal hopper and moves along the grate to undergo combustion. The burnt coal cinder is then discharged at the end of the grate. This type of boiler is widely used in industries such as food, paper, construction, cable, electronics, tobacco, and textile for processes like drying, disinfection, ster...
Exploring the industrial boiler sector often brings up the question: "How much coal does a 1-ton steam boiler consume annually?" This inquiry not only reflects users' concerns about boiler efficiency but also hints at considerations regarding operational costs. Although the question seems straightforward, it underscores deep concerns about energy utilization efficiency and environmental protection.
Firstly, the annual coal consumption of a "1-ton steam boiler" is a complex calculation influence...
In the whole drying process, we should pay attention to gradually increasing the temperature instead of burning by raging fire; regularly checking boiler's water level and keeping it within the normal range; keeping the flame balanced in the furnace. In addition, we also should properly open the drainage valve and maintain the water level, regularly record the flue gas temperature to control the rise of temperature and high temperature and keep the temperature within the normal range. In general, under these conditions, boiler’s drying quality can be ensured.
The air oxygen content's effect on the boiler is mainly reflected by the effect on the blowing rate. Boiler will have typical phenomena if the blowing rate is high or low.
The coal-fired boiler has always been one of the important boiler types in the industrial production and its operating costs and capacity play an important role in the enterprise operation.
Because coal fuel is expensive and coal combustion can cause serious environmental pollution, it is necessary to transform the coal-fired boiler into gas-fired boiler. However, the reconstruction of coal-fired boiler is not a small project. Only pay close attention to every phase of the reconstruction process can avoid failure.
(1)Ensure normal and stable steam pressure, steam temperature and evaporation.
(2)Avoid coking and burner damage; Ensure the safety of the operation of the superheater; Reduce pollution of combustion.
(3)Make the operation achieve the highest economy.
If the pumps of a coal-fired boiler are not absorbing water, it could be due to several reasons. It's essential to diagnose the issue accurately for an effective solution. Here are some common causes:
Air Locks in the Pump or Suction Line: If there is trapped air within the pump or the suction line, it can prevent the pump from creating the necessary vacuum to draw water.
Low Water Level in the Feed Tank: If the water level in the feed tank is too low, the pump may not have enough water to dra...
