High temperature or below the rated temperature of the device, will have a bad effect. If the temperature exceeds its rated value, the prices cleaver brooks boilers will cause overheating of the relevant metal material, material creep acceleration, will shorten the life of the boiler. If the temperature is too high, but some of the key components of the boiler would cause damage, can also cause serious and even superheater tube rupture. If the temperature is lower than the rated temperature, vapor enthalpy is reduced, increased air consumption, decreased economy. This will reduce the thermodynamic cycle efficiency of the plant, the steam humidity at the last stage blades of the gas turbine increases, causing erosion and damage to water droplets gas turbine blades, affect the safe operation of the gas turbine.
3,4 units of 5.6MW hot water boiler.
In Harbin fifth session of the Fourth Session of the National People's Congress, coal-fired prices cleaver brooks boilerss 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.
4 tons of gas steam prices cleaver brooks boilers blowdown should pay attention to what matters should be ① the sewage at low load, high water level. Close attention should sewage water level in the furnace, each sewage water level in the boiler to reduce the 25 to 50 mm is appropriate. ② if not through to the sewage outfall end of the tank or sewage well, and no protective equipment must be available in the sewage do know that no one is near the outfall place to avoid accidents when sewage. ③ particular sewage operation is as follows: two with each boiler blowdown valve, the first (the one away from the boiler) when only the second full discharge, then only slightly open first drain valve (latest one from boiler) to preheat the pipe until the pipe gradually turn up after preheating only a first drain valve, the sewage must be completed first gradually turn down the drain valve, shut off and then only the second drain valve, the purpose of doing so is to use only the first discharge, when leakage to keep only the first, only the second control emissions can still be used. When sewage if there is impact noise in the sewage, that is only the first drain valve should be closed until the small impact sound disappears, then slowly turn up the sewage should not be carried out continuously, so as not to affect the water cycle. ④ After the completion of the sewage close the drain valve, the drain valve is tight check, check is: closing the first drain valve only after some time, the second test only touch on the drain valve conduit hand, if the cooling blowdown there must be leaking valve.
