The boiler gas consumption calculation need the following parameters: gas calorific value and boiler thermal efficiency. Theoretically, the gas consumption of boiler = boiler thermal capacity ÷ (calorific value of gas x boiler thermal efficiency ) Take the 1 tph steam boiler as an example: = 600,000 cal / (8500Kcal * 0.98) =72m3/h, the 1 tph boiler's gas consumption per hour is about 72 cubic meters.

Water, which is the primary fluid inside the closed metal container of the industrial boiler, is heated to an atmospheric temperature and a pressure higher than the external one. Once the steam is generated, it advances through the pipes.

Biomass steam boilers recover the heat generated during the biomass combustion process to heat the water in the boiler exchanger circuit. The hot water is then diverted to the heating circuit. Occasionally it is necessary to remove the ashes generated by biomass combustion and clean the burner.

Question details (performance):Black smoke happens during operating. Answer: Fault reason:(1) Insufficient air volume, improper air distribution, low furnace temperature: boiler usually equipped with air preheater, but when the air preheater has leakage, hot air flow doesn't satisfy the need of burning, smoke will happen.(2) In the case of stalling situation in full automatic oil-fired boiler: significant increase of furnace negative pressure, no flame can be seen from the inspection hole, steam pressure and steam temperature drop, the steam flow decreases sharply. The water level drops suddenly and then rises sharply.(3) Incomplete fuel burning: this is the main cause of boiler smoke, in the operation, some combustible gases such as carbon monoxide, hydrogen, methane will be generated in addition to carbon dioxide, sulphur dioxide, water vapor and oxygen, nitrogen, etc. during incomplete combustion. They burn and generate black smoke. Incomplete combustion of fuel will not only lead t

(Question Details) Specific Performance:The pipe of superheater bursts in circulating fluidized bed boiler operation.The bed pressure indicator fluctuates little. Answer:  causes of failure:(1) Design Factors.(2) Manufacturing process, installation and maintenance quality.(3) The temperature control device is unreasonable or does not work properly.(4) Effect of operating conditions on overheating and explosion of superheater. Troubleshooting:(1) Report the fact to operator on duty and require operating the boiler in low load.(2) When the overheat damage is serious,please report it to operator on duty and require stoping the boiler immediately to prevent blowout of the near pipes.(3) Adjust the steam temperature as much as possible within the normal range.(4) If the superheater tube is not damaged badly, it has little effect on the temperature level of the steam, and it can be allowed to run in a low load range for a short period of time.
