circulating fluidized bed boiler operating principle

Advantages premix circulating fluidized bed boiler operating principle module 1. Safety: premix combustion, controlled combustion conditions, combustion stability. Compared to traditional boilers, boiler module premix is ​​no security risk due to excessive pressure generated, and hot water delivery is also easier to control than steam. 2. Environmental: compared with the conventional air combustion, boiler module premix premix combustion technology, more complete combustion, flue gas of small size, low pollutant emissions. By the departments of State authority, NOx emissions below 30mg / m³, CO emissions lower than 90ppm, and in line with better than national standards and European standards. 3. Intelligent: modular multi-parallel control, parallel controller can initiate the system out of the water temperature according to its own distribution, the number of equipment units outage, heat to achieve dynamic balance of supply and demand, without staff on duty, to avoid over-heating and heating shortage situation. Durable: premix heat exchanger using boiler module interfaces without welding process, the weld due to eliminate the risk of corrosion and leakage fundamentally made of stainless steel, long service life. Accessories used mainly industry-leading brands to ensure the stable operation of the equipment. 4. Energy: operating at a low temperature, the thermal efficiency of the boiler module premix up to 108%: integrated thermal efficiency of 105%. Far more than the state's level of energy efficiency indicators! Traditional and atmospheric gas boilers compared to gas savings of up to 35%. 5. Light-owned: premix changed the traditional boiler module "with a preparation of" operating mode, each high mutual backup module, equipment investment and utilization. Single small module size, light weight, easy to transport. Once a module fails, the whole system does not have to stop running, easy maintenance.

A strict circulating fluidized bed boiler operating principle installation access. For newly installed boiler strictly enforce provincial and municipal environmental policy, a full cessation of 35 tons and below, installation and construction of coal-fired boilers to inform, installation supervision, inspection and use of registration, to cooperate with the elimination (dismantling) work.

Second, the coal-fired boiler using a registration certificate cancellation notice. According to regulations, the original registration for the 83 and 10-ton coal-fired boilers using the write-off registration certificate shall be published on the government website, while informing the inspection unit will not be tested.

Third, strengthen supervision and law enforcement boiler safety, to promote the phase-out of coal-fired boilers. The boiler safety supervision and law enforcement with prevention and control of air pollution combine to crack down on illegal installation of boilers, illegal use, not extended inspection, not extended rectification risks and other illegal acts, to perform their duties according to law, to promote the phase-out of coal-fired boilers smoothly. This year we have gone through all kinds of boilers 117 units, of the 10 units are still using coal-fired boiler inspection found, ordered to stop using and timely communicated to the relevant environmental authorities and the town street, cooperate with the 10 coal-fired the dismantling of the boiler.

Third, the condensing gas circulating fluidized bed boiler operating principle equipment parameters and specific circumstances do not apply. Adaptability condensing boiler and to ensure that the environment is substantially ensure stability of the system must first determine the various parameters of the interface where the boiler system itself good in the purchase history of a long-condensing boilers, thermal energy value, pipe size, the space available areal extent, so as to determine the appropriate model parameters and condensing boilers combined with the original use of the energy system, so it can ensure an actual condensing boiler with the same use environment.

Party hot water circulating fluidized bed boiler operating principle fast boiler equipment specializing in the production of clean fuels over twenty years, now has 120,000 square meters of intelligent manufacturing plant, the construction of a national standard R & D labs across the country are uniformly distributed sales and service outlets service points, more than the annual output of 20,000 tons of steam.
