procedure of starting fire tube boiler

Main steam procedure of starting fire tube boiler 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.

The gas condensing procedure of starting fire tube boiler quality discern what to see? Gas condensing boiler is now a new type of energy-saving and environmental protection equipment, its working principle is to use exhaust gas temperature of the heat so that it can once again be fully utilized, greatly improving the thermal efficiency of gas, but also in the process of using the exhaust gas some harmful substances can be removed gas flue gas emissions are purified. With the market can supply gas condensing boiler manufacturers gradually increased, then how do we distinguish from a wide range of products in a reliable, high-performance gas condensing boiler it? According to the grades of gas condensing boiler use. Quality discrimination gas condensing boiler must first determine its good grades, since the gas condensing boilers require prolonged contact with the condensate water, and impurities in the condensed water may cause it to have a certain acid or oxidizing, and therefore, the material selected must be resistant to high grade ferritic stainless steel, austenitic stainless steel or aluminum body, in order to ensure its long-term use. Production technology strength based manufacturers. Quality distinguish gas condensing boiler should also be appropriate for the respective manufacturer's technical mastery in the identification, manufacturers set up a long time the capital chain solid and reliable, with a complete set of unique technology of condensing boilers mature production technology, and have a gas condensing boiler function improvement and development, it is a strength of the manufacturers out of the production and processing of natural gas condensing boiler equipment performance worthy of belief. Visual evaluation of the equipment in accordance with long-term customers. To identify the quality of the gas condensing boiler can be confirmed by evaluation of user success stories of his company served, hot gas condensing boiler necessarily a large number of factories and supply a variety of customer gas condensing boiler equipment, and has for many users the highest rating aftermarket, quality, service attitude.

Condensing gas procedure of starting fire tube boiler working principle and key points: the concept of condensing gas boiler condensing gas boiler, by definition is condensing gas boiler, condensing gas boiler can now be divided into commercial gas condensing boilers and industrial gas condensing boiler, condensing the product is the difference between the horizontal vertical boiler and condensing boiler two series. The most important is to realize the nature of condensing technology which condensing gas boiler.

Fangkuai Boiler is based on low-nitrogen energy-saving and environmental protection. It focuses on the development trend and uses universal excellent technology, products and services. According to such a method, it is now applicable to the development of society around the world, promotes cutting-edge work in the future manufacturing industry, and maintains the ideal use of customers in various industries.
