boiler waste heat to power generation

Pharmaceutical formulations employed and the amount of alkali cleaning method according to the specific circumstances of the gas boiler waste heat to power generation. Commonly used soda ash - tannin or alkaline detergents and the like. Alkali cook, cooking oven may be employed without pressure, less than the time (the time scale is thick, can be extended) 24h, in order to improve the cleaning effect of alkali cooking may be lye cycle, the higher circulation rate, the descaling the better.

Henan Notes boiler waste heat to power generation gas leak problem Henan precautions gas boiler leaking problem: ① the inner wall of the Henan gas boiler leaks: leak is also divided into the inner wall of the drum and the provision of water leakage and water cooling pipe leakage drop, if the former is relatively small leakage eye, can be Wabu same steel, after Patching flaw detection. Leak needs to be replaced before the tube, replacing a large area. ② Henan leaking gas boiler handhole: re-try transducer mounted at an angle, to see if there is a hand hole cover deformation, if deformed, the first correction, and then the green tape wrapped in a layer of a uniform mat, and preferably consistent position before overhaul . ③ gas leak in the boiler drum: the higher cost of repair costs, mainly to see the location and size of the leak leak point where, if the old boiler appears oozing red pot of water, indicating that water quality problems, probably because of low alkalinity or water metal corrosion caused by dissolved oxygen is too high. Low alkalinity can adding sodium hydroxide or trisodium phosphate to a pot of water, dissolved oxygen in water is too high to be resolved by the deaerator. ④ leaking water treatment system: first check whether the gas boiler corrosion, if you need to descaling the boiler corrosion, leaks repaired part, and then circulating water treatment, adding agents, equipment and other materials were boiler corrosion, scale, protection . ⑤ boiler flue gas leak: check is not the boiler tube or tube sheet due to cracks, if the need to change the pipe, see Wabu flue used material, aluminum, and stainless steel may be carbon steel or argon welding aluminum wire, iron acid electrode material directly. ⑥ leaking valves: Valves leaking packing should be added to or replacement of the valve.

Recently, we learned, Shaoxing City, Zhejiang Province People's Government Office issued the "coastal city 2018--2019 autumn and winter tackling air pollution comprehensive management action plan", as follows.

Less adopt comprehensive measures to reduce coal total coal consumption, coal consumption in 2018 to ensure that the total amount of negative growth. New non-owned coal-fired units, the implementation of new large-scale coal-fired units and coal consumption capacity equal or reduction alternative.

Optimize the use of natural gas structure, in principle, to new natural gas cogeneration and gas chemical projects, gas will adhere to the reform, orderly manner "coal to gas" project.

Carry out boiler (with tea furnace, operating a stove, grain storage and drying equipment, coal-fired facilities) an intensive investigation to establish accounting and inventory management, to develop a comprehensive remediation program in accordance with the unified deployment requirements boiler city, according to the law in accordance with regulations to increase fuel coal boiler out of efforts to achieve all cleared 10 steam tons / hour and coal-fired boilers to prevent high-polluting fuel boiler rebound has been eliminated. Boiler registration strictly prohibit new steam per hour 35 tons / hour of coal-fired boilers, coal-fired boilers new emission concentration to meet ultra-low emission of air pollutants, strict control of new biomass boilers, coal-fired boilers embodiments and low nitrogen urban built-up area of ​​ultra-low emission biomass boilers transformation.

In the case where the fuel consumption is constant, the lower the heating system return, the more condensing heat recovery heat recovery, the higher the thermal efficiency of the boiler waste heat to power generation. Using condensing gas boiler than ordinary gas boiler can save more operating costs.

1 million kcal / h boiler, for example, natural gas consumption of the conventional type boiler 126.5Nm³ / h (natural gas low heat value 8500kcal / Nm³), consumption of natural gas condensing boilers 110Nm³ / h, when the boiler is operating 10 hours a day, heating period of 100 days, then the use of natural gas condensing boiler annual savings 16500Nm³, natural gas price of 1.8 yuan terms, annual savings of operating costs 29,700 yuan.
