pressure chincoal fired steam boiler

In Harbin fifth session of the Fourth Session of the National People's Congress, coal-fired boilers governance as a key task to be mentioned again. Meeting specific targets: by 2019, Harbin will govern coal-fired boilers, boiler out of 35 tons and below do not have to upgrade conditions, starting 65 tons or more of coal-fired boilers and energy-saving ultra-low emissions transformation.

2019, Harbin will continue to strictly control the total amount and quality of coal, according to local conditions to solve the shanty towns, suburban town (township) village coal powder burning problem by briquetting, Burying to field, the way raw material cogeneration, effective path to explore the comprehensive utilization of straw, the straw open-air Jinshao continue to focus on the work to implement the required emission limits industrial emissions, car exhaust strengthen, kitchen fumes, dust and other site management, effectively improve air quality.

2018, Harbin City, air pollution, elimination of coal-fired boilers 1191 units, biomass boilers to replace more than 10,000 units, updated bi-fuel taxi 1270 units, 1323 units of new energy buses, comprehensive utilization of straw and prohibiting open-air work strength forward, ambient air quality fine days up to 312 days, an increase of 42 days over the previous year, the highest level since the ultra-high PM2.5 monitoring.

The reason is that we are mounted in the boiler temperature sensing device, the sensors during operation equivalent to our human eye, the accuracy of the boiler operation to transfer data in the form of boiler control means, the control means after receiving the information to automatically adjust the temperature, thus completing the automatic control of the temperature of the gas boiler.

How to improve the thermal efficiency of gas boiler? The main method of increasing the thermal efficiency of the gas boiler, gas boiler main saving measures taken are the following: 1 ratio control and adjust the ratio of air and fuel gas, the fuel gas to obtain sufficient combustion; = 2 should be strengthened and heating furnace. heat pipe network to reduce unnecessary heat loss, which is generally used in the boiler room way; 3. strengthening treatment, and prevent tube fouling drum, good heat transfer efficiency; pre-fired boiler by tail device, add some air preheater;. 4 in particular of the heat recovery condensate; 5 scientific design many heating boilers should flow back and forth so that the water should have a reasonable temperature difference; thus, it enables to improve the thermal efficiency

To introduce preventive measures for pressure chincoal fired steam boilers and common faults of steam reciprocating pumps and measures for handling them, 1. Adequate and effective fire fighting equipment should be provided in the vicinity of steam boiler houses. 2. Steam boiler rooms must have staff on duty 24 hours. Watch in turn, constantly check the water mark in the boiler, ensure above the safety line, prevent dry burning from causing explosion. If you start a fire operation in a flammable and explosive place, you must obtain a fire work permit and do enough fire prevention measures before you can start a fire operation. When you start a fire, you must set up a special person on duty and observe the fire situation at any time. 3, It is strictly prohibited to store containers containing combustible gases in boiler rooms. 4. Steam boiler rooms The personnel must be on duty with a certificate, and master the boiler operation technology skillfully, and have a certain ability of discovering and recognizing hidden dangers of safety. 5. In accordance with the boiler operating instructions, the boiler shall be safely overhauled regularly, Every unsafe factor should be carefully checked in the inspection. 6. The distribution lines installed in the steam boiler room shall be protected by metal pipes or non-combustible rigid plastic tubes, and switch boxes shall be installed separately outside the boiler room, so that the power can be cut off. Prohibition of the use of unqualified safety devices. 1. What is the reason why the steam reciprocating pump does not discharge liquid? How do you rule it out? Answer: (1) cause of failure: 1 suction or discharge line clogging. 2 in, drain valve stuck. 3 in cylinder There is air. 4 suction line connections are not tight. 5 column (live) plug sealing rings are seriously damaged. (2) removal method: 1 removal of pipeline blockage. 2 clearance of plug in drain valve. 3 filling of water. Clean air. 4 fasten line. 5 replace column (active) plug seal ring.
