1, the low-pressure water tube double drum boiler
Endothermic features: low pressure boiler, a large latent heat of vaporization. The heat of evaporation, less thermal overheating;
Hot water water tube double drum boiler stratified combustion hot water boiler stratified combustion hot water boiler stratified combustion in the implementation of these advanced skills! Its main effect is that! Because of loose coal! Coal layer permeability is good! Outstanding air and coal touch! So combustion rate gets progressively, the transformation of coal plus device tiered coal bucket! way using mechanical sieving! coal-fired formed at a small coal particles large! stratification uniform distribution of coal thickness before entering the furnace! coal seam gap uniform! ventilation outstanding! get rid of attack crater and run coal leakage! firepower to reach the # 1 step-up temperature, fast! stable combustion, stratified combustion selection skills can improve furnace temperature (223 mercy! while strong on coal adaptability!, dry wet coal are applicable, the use of energy-saving significantly on the chain furnace! use in the performance of various tonnage boiler is heating up fast! contribute good! reduce carbon content of ash at the mercy of a lot of people in the 5 boiler operation 4) * (2) often negligence burn rate simply seeking to decrease the carbon content of ash! actually ash carbon content of the check is necessary to ensure that additional burn rate in the first condition to be effective in practice often to see! boiler load at 42) the case! ash carbon content is fully able to (2) the following! This check is not scientific, stratified combustion at the same time can improve the combustion rate can drop ash carbon content! It should be said for the improvement of combustion conditions played a real effect! We should continue to implement and practice continue to improve this skill, that is more than hot water boiler stratified combustion effect.
Say the existing boiler models on the market, then it is countless, but from the looks of it, there is a cylindrical, vertical, horizontal, etc., these are more common in older boiler room. And in some newly built boiler room, one Taiwan "modular" better known and boiler use.
Dongying City, Shandong Province in response to low-nitrogen coal-fired water tube double drum boilers, industrial waste heat recycling and other environmental policies, combined with local conditions, Dali urban and rural areas to promote clean heating projects, and achieved remarkable results. As of mid-October this year, Dongying City clean heating rate of more than 72%.
Recently, Dongying Municipal Urban Management Bureau to the outside world, in order to further promote the urban and rural clean heating, it has already shut down 10 coal-fired boilers environmental non-compliance of a total of 155MW.
After shutting down 10 coal-fired boilers environmental non-compliance, Dongying City high environmental standards were established in a total of four 58MW gas-fired boiler and a total of four 70MW coal-water slurry boiler through a series of energy-saving treatment, flue gas emissions much higher than the index of new environmentally friendly ultra-low emission requirements.
Meanwhile, Dongying City, the original heating effect is also unsatisfactory 4.33 million square meters of heating regions to establish a uniform heating systems, and the use of standards to ensure clean heat source; higher operating costs for the original 2.17 million square meters of heating area heat source replacement process, both to ensure good heating effect but also saves a lot of money.
According to statistics, this year the city of Dongying city plans to add a total area of clean warm 8.1138 million square meters, down to the next new clean heating in rural areas 45000.
Recently, Dongying City issued a "Dongying City 2018-- 2020 coal consumption reduction alternative work" (the "Program"), after the completion of the city's 10 steam tons / hour and small coal-fired boilers zero and start steaming for 35 out of work t / h coal-fired boilers and, as of 2020, out of 35 steam tons / hour and coal-fired boilers.Free Chat
