One of the main factors of high temperature corrosion of boiler water wall is seriously affecting the safe operation of the unit, solve the problem of water wall high temperature corrosion of boiler operation has a good long-term stability of the practical benefits.
Main steam heating surface area of water tube boiler formula gas valve and other valves, and a predetermined baffle flue gas system 1 shall be clearly marked boiler tubes, valves and dampers marked name, number, and media flow direction switching direction, should the main regulator valve for opening degree indication. Valve, the shutter operating mechanism should be installed at a location convenient to operate. 2 main steam valve should be installed near the outlet of the drum (potshell) or the header of the superheater. Boiler unit consisting of machine, the main steam valve the inlet of the turbine can be installed. Main steam valve vertical shell boiler may be installed in the boiler room to facilitate local operations. On each boiler steam pipe with steam header pipe is connected, cutting two valves shall be installed, it should be equipped with a drain pipe and cutting the valve between the valve open to the atmosphere, an inside diameter not less than 18mm. 3 evaporation rated greater than or equal to 220t / h boiler to be provided to the remote air exhaust valve. Fractional economizer inlet 4 can not be fitted to the water supply pipe and the water supply valve shut-off valves. For unitary unit, not fitted with a check valve to a water tube boiler feed water. The inlet of the economizer and separable leading drum (potshell) are mounted to the water supply pipe should be cut off the water supply valve and check valve. 5 feed water shut-off valve should be mounted between the drum (boiler shell) (or economizer inlet header) and a water supply valve and the check valve immediately connected with the water supply. 6 in the rated evaporation 4t h boiler / automatic water regulator shall be installed, operated and easy to place in the installation manual means fireman who feedwater control. 7 rated steam pressure is greater than or equal to 3.8MPa boiler pipes should be urgently put in a minimum security indirect drum water level and normal water level, discharge pipes should be installed on the valve, once full of water occurs in order to promptly turn on the water. This valve must be turned off in the boiler running. 8 in the drum (potshell), superheater, reheater and economizer, etc. which could gather air should be fitted with an exhaust valve. Different operating pressure of the boiler 9 should have a separate steam pipes and water pipes, respectively. When employed as a main steam pipe, the steam pipe must have a higher pressure automatic decompression device, and a safety device that prevents the low-pressure side of the overpressure (check valve). When the water pressure which does not exceed the maximum working pressure of 20% of the total water supply can feed water to the boiler system. 10 boiler feedwater system should ensure safe and reliable water supply. Boiler room should have an alternate water supply equipment. And the number of spare capacity and a water supply device is arranged water supply system, is determined by the design of the boiler room units according to the design specifications. 11 rated greater than or equal to evaporation 1t / h boiler water sampling device should pot, when steam quality requirements, there should be vapor sampling means. Sampling means and the sampling point location should be taken to ensure that water vapor representative sample.
Fuel volume adjustment simple mechanical atomization nozzle adjustment range is usually only 10% to 20%. When the heating surface area of water tube boiler formula load changes little, the oil pressure in front of the boiler can be adjusted by changing the oil pressure before the furnace, and the purpose of increasing the oil pressure can be achieved by increasing the oil pressure. When the boiler load changes greatly, the atomization plate with different aperture can be replaced to increase and decrease the fuel injection. When the boiler load changes greatly, neither of the two adjustment methods can adapt to the requirements, so it is necessary to change the fuel injection quantity by increasing and reducing the number of fuel nozzles. The adjustable range of the atomizing nozzle of the return oil machine is relatively large. When the boiler load changes, the return valve opening can be adjusted accordingly to change the return oil quantity. Return oil The larger the quantity, the smaller the injection quantity; on the other hand, the fuel injection quantity increases. In normal operation, the fuel quantity shall not be increased or reduced sharply, so as not to cause the sharp change of combustion, and cause the pressure element to expand and shrink abruptly and damage.
Anyang City Minshan Nonferrous Metal Co., Ltd. is a collection of urban mining, renewable resources, energy as one of the economic wisdom of cleaning companies, mainly non-ferrous metal extraction and processing work. Company to conserve energy, cleaner production for the purpose of this concept coincides with the fast heating surface area of water tube boiler formula.
