The boiler chimney is one of the essential facilities in the process of building a gas boiler room. Its main function is to provide ventilation for the hot flue gas or smoke emitted by the boiler. Usually, when making the chimney of gas boiler, choose the vertical structure as much as possible to ensure the gas flow smoothly, and the sucked air enters the so-called chimney combustion or stack effect.
The first reason is unreasonable structural design.
In the operation of chain grate boiler, uneven distribution of short coal seams in grate, improper adjustment of coal feeder, unreasonable control of coal seams and poor regulation performance of air supply volume in air chamber will all lead to insufficient burning of coal.
The second reason is unreasonable setting of secondary air.
If the primary wind speed is too high, the air volume is too large, and the air rate is too large, the pulver...
Chain grate boiler is a very mature boiler type, which has the characteristics of simple operation and management and easy mastering, and is widely used in various industries.
1. Enterprise qualification
Which manufacturer is good, enterprise qualification is the first. On the whole, enterprise qualification reflects the enterprise's personnel quality, technology and management level, engineering equipment, capital and benefit, contract management ability and other aspects. Genera...
When purchasing the gas-fired boiler, the enterprise will generally require to visit the boiler factory at the later period of boiler procurement. Via visiting the boiler factory, the enterprise can have a comprehensive understanding of the operation process, production scale, product quality details, corporate management level, factory shipment and other information of the boiler factory, and can further understand the service quality of the boiler manufacturer.
Gas-fired boiler is a kind of thermal equipment that uses the thermal energy released by fuel combustion or other thermal energy to heat the medium to the rated temperature. With the strict environmental protection, gas-fired boilers are widely used in power generation, heating, factory processing and so on. Boiler thermal power refers to the continuous heat production per unit time of hot water boiler at rated parameters, rated flow, designed fuel and guaranteed efficiency. So how to convert th...
Modular gas-fired boiler, according to the user's load and design needs, combines several independently operating module units into an integral boiler. By monitoring and calculating the changes of indoor and outdoor temperature and temperature of supply and return water, the computer automatic control system can control each level of modules, automatically adjust the number of modules to start and stop, make the output heat always match the actual required heat load, and ensure that each module ...
1) The insufficient heating surface. In the process of retrofit design or improvement, increase the heating surface.
2) The particle size of the fuel is large, the screening characteristics do not meet the requirements, the material concentration in the suspension section is low, and the heat transfer coefficient is small, which makes the output unable to go up, or shows that the bed temperature is high and coal cannot be added. The solution is to improve the fuel preparation system and control...
ATMOSPHERIC BOILER - a boiler in which combustion air/flue gases are drawn through the boiler without a fan. Modulating atmospheric boilers are designed to control the output (size of flame) to match the boilers variable load requirements. During this process the burner is designed to stay at the correct fuel / air ratios across the complete firing range ensuring maximum combustion and boiler efficiencies. Modulation refers to a boiler's ability to match firing rate - input - to meet the heating demand - output - of the system. (https://tlj-eng.com/news/heating-boilers-what-you-need-to-know.html)
