Question details (Performance) :
1. The vibrating coal grate stops running totally or intermittently.
2. The current of vibrating coal grate motor rises abnormally.
3. The safety clutch of transmission machine of grate or safety pin is broken.
Answer: cause of the problem:
Boiler’s vibrating coal grate is a rotating combustion equipment, due to the bad working conditions, stuck stalling is easily happened and grate failure happens in daily application and ...
In this question, what is the tonnage of a 6 million kcal boiler? Tonnage and 10,000 kcal are the expressions of boiler heat supply or boiler capacity. However, the relationship between different representations is unclear to many users.
Boiler capacity unit
Before the announcement of the equivalent tonnage of 6 million kcal boiler, the common boiler heat supply units in China were summarized:
Kcal/hour (Kcal/h) is a metric unit, which means the heat that the boiler can provide per ...
Prepare relevant technical data, including technical data of boiler manufacture and installation, boiler use registration data, boiler operation records, water quality test records, repair and modification records, accident records and previous inspection reports;
Ensure that the vent valve on the boiler is open and check there is no pressure in the boiler. Check that the steam stop valve is closed. Check that all the valves for fuel are open, and let the fuel circulate through the system until it comes to the temperature required by the manufacturer recommendation.
All boiler pipes have been installed and passed the hydrostatic test.
The furnace wall masonry and insulation work have all ended and has been qualified.
The flue gas duct has been installed and insulated, and the induced draft fan has been installed and debugged to be qualified and can be put into operation.
All the thermal and electrical instruments required for boiler drying have been installed and verified to be qualified.
Mortar samples have been placed on both sides of the middle par...
Chain grate has certain selectivity for coal types, and soft coal with volatile content above 15%, ash melting point above 1250℃, moderate particle size and calorific value above 18800~21000kJ/kg is more suitable.
A 10 tph boiler does not mean that the dead weight of the boiler is 10 tons. The ton of the 10 tph boiler is the heat load unit of the boiler, which is used in engineering, indicating that the rated evaporation capacity of the boiler is 10 t/h.
The rated output of boiler refers to the maximum sustained output of industrial boiler under rated parameters (pressure and temperature) and certain efficiency. For steam boilers, the rated output is also called rated capacity, and the unit is t/h (tons/hour); For a hot water boiler, the rated output of the boiler is also called the rated thermal output, and its unit is MW.
