Background technology
Boiler needs burning fuel, when burning fuel, in the presence of high temperature, and the nitrogen and oxygen in air are easily sent out
Raw combination reaction, forms the oxynitrides polluted, and because the burn incompletely of fuel can produce a substantial amounts of oxidation
Carbon.Existing boiler is all difficult to solve this problem, because most cheap oxidant is exactly air, but the nitrogen content in air is again
It is very high.In order to reduce oxynitrides, tail gas is allowed to meet discharge standard, many boiler for producing commercial cities have to reduce boiler
Fuel feed speed, lay multiple burning points, allow fuel to try one's best the oxygen exhausted in air, to reduce the production of oxynitrides
It is raw, but this can cause the efficiency of boiler to substantially reduce again.
Boiler needs constantly to supplement water constantly to produce steam, and water could be stored in water tank.Because the need of energy-conservation
Will, often recovered steam is condensed into the higher water of temperature and is stored in water tank for present boiler, the case for the water tank of boiler
Interior pressure can change with the temperature change of dampening, existing water tank in order to avoid tank pressure it is excessive and under tank seal performance
Drop, leak, the situation of fried case occur, and existing water tank is all to have normally opened steam vent, to ensure that the pressure in water tank is constant.But
It is that normally opened steam vent can cause the loss of heat, this just unusual not energy-conserving and environment-protective.
