Reference for matching based on coal-fired design of boiler for power plants for SMEs Many SMEs in matching coal-fired boiler will always encounter do not know how to judge its quality of authenticity Di distress, then, Eastern Machinery As a person in charge Di manufacturer, special summarize three elements for each business owner a reasonable option. 1, first the amount of evaporation, the capacity of the boiler should be close to the maximum amount of steam produced or with heat. Preferably, the amount of steam production is about 80% of the rated boiler evaporation. Because the loss of pipe, boiler scale, soot and so will cause the boiler deviates from the ideal operating conditions such as. The need for additional reminder, evaporation is the evaporation of the boiler plate under pressure, while some foreign boiler that evaporation is zero amount of evaporation reduction, the actual boiler output vary greatly. 2, when the feed water temperature is the same evaporation plate, boiler feed water has a temperature of 20 ℃, 60 ℃, 90 ℃, 100 ℃, 105 ℃ are five. Due to the high and low water temperature, the actual boiler evaporation will have a greater difference. For example: there is a large difference output 20 ℃ boiler output water temperature and water temperature of 100 deg.] C. 20 ℃ boiler output water temperature is 114% of the output water temperature of 100 deg.] C. 3, the pipe resistance rated steam pressure should be greater than the sum of the boiler plate steam supply pipe resistance and operating pressure needed for the production. Do not overlook the steam pipe resistance, due to its higher rated steam pressure saturated steam temperature is higher.
Condensing gas design of boiler for power plant and process water hammer phenomenon condensing gas boiler 1. The water hammer phenomenon: (1) gave a regular crash condensing gas boiler and in the pipes, sometimes loud sound, accompanied by strong vibration water pipes or steam pipes. (2) gauge pointer swings back and forth, the frequency of sound and vibration consistent. (3) water hammer severe, it may lead to the respective connecting members, such as weld cracking, breakage of the valve. Processing the drum 2. Water hammer: (1) check valve malfunction, combustion should be reduced to reduce the load and pressure boiler feed water shut-off valve closed to stop the water supply, the water supply valve repair quickly. At the same time we should observe the water level to prevent water accidents. (2) means for heating the steam drum when Stokes, should quickly close the steam valve. (3) maintaining the water level in the boiler condensing gas uniformly into the water balance drum. Water hammer is still ongoing, it should be shutdown for maintenance. (4) boiler maintenance, should strengthen water supply, water distribution and water tank repair. 3. The steam treated water hammer pipe: (1) reduced steam supply, close the main steam valve if necessary. (2) Open the trap set on the superheater and steam pipes hydrophobic tank. (3) drum level is too high, the sewage should be appropriate to maintain the normal water level. (4) strengthen water treatment work to ensure water supply and boiler water quality, prevent priming. (5) elimination of water hammer, check the pipe and pipe rack case, flanges, etc., as the case without further heating pipe for a steam supply.
Oriental Hawaii Holiday Hotel is located in Xiaogan City of Hubei Province in accordance with international five-star hotel standard design, set business rooms, SPA bath, foot care, indoor spa and other facilities in one of the hotel. Hot water design of boiler for power plant is one of the important facilities normal operation can not be separated. With the pace of Hubei Province in response to the national defense of the blue sky, the use of clean fuels gradually increase the proportion of Oriental Hawaii hotel provides visitors to the more perfect leisure experience a sense of the original wishing more polluted coal-fired boilers to replace clean and green gas-fired boiler. After comparing several vendors boiler industry, a number of R & D results very fast square value in the field of clean fuels, entered into a collaboration with the fast boiler. Fast boiler integrally provided a 1.4MW condensing pressure hot water boiler (CWNSL1.4-95 / 70-Y.Q) according to their actual needs. Put into use, fully meet the needs of Oriental Hawaii Holiday Hotel heating and hot water supply.
Are there any prescribed steps for the start-up and shutdown of hot-water design of boiler for power plants? There are prescribed steps for the start-up and shutdown of hot water boilers. When the boiler starts, the circulating pump is operated first, then the burner is ignited, while the boiler stops the furnace, the burner is stopped first, and the circulating pump is operated for a period of time before it stops. However, in the way of operation, the traditional operation is manual operation. With the development and progress of technology, the computer control operation can be realized to replace the manual operation. Moreover, the procedures can be set by the program, so as to avoid error operation.
