The theory of thermal power station or working of thermal power station is very simple. A power generation plant mainly consists of alternator runs with help of steam turbine. The steam is obtained from high pressure inside a bagasse fired boilers. Generally,bituminous coal, brown coal and peat are used as fuel of boiler. The bituminous coal is used as boiler fuel has volatile matter from 8% to 33 % and ash content 5% to 16 %. To increase the thermal efficiency, the coal is used in the boiler in powder form.
"Coal to gas", "coal to electricity" is the trend in recent years of China's reform inside a bagasse fired boilers, all regions are gradually improving. But because some areas coal to gas, coal to electricity-related project has not been completed, the pipeline can not be normal delivery of natural gas and electricity, but there can not ban the use of burning coal for heating, resulting in some of the people cold.
Under Thus, this year, Hebei Province, will carry out the inspection work cleaning heating dragnet, scheduled for November 1 to 10, requires each village and household dragnet inspection, the gas supply, power supply is not guaranteed to get the premise not allowed to first dismantle heating stoves.
Inspection team is more than 2,000 people drawn from the province's environmental protection system, divided into 120 large groups, each group of sub-1-2 large counties (cities, districts), take the main city limits off-site inspection, cross-check each other, such as thorough investigation way, a comprehensive understanding of coal to gas, coal to electricity and clean coal work on behalf of the double security for the situation.
Wherein, the village 500 (cell) is not less than 20% of households checks; 500 villages and above (cell) checks no less than 10% of households. The main inspection five aspects, including: gas supply, power supply security, security for the clean coal and distribution, development of contingency plans, etc. under extremely adverse weather conditions. In gas supply, power supply is not guaranteed under the premise, the focus in advance to see if the removal of heating stoves situation.
Environmental Protection Department official said earlier this year in northern clean heating to proceed from reality, insist on the need for constant, the gas will change to ensure that clean heating and warm winter are guaranteed.
6 tph WNS condensing gas-fired steam inside a bagasse fired boiler to Inner MongoliaXincheng Hotel is the first five-star hotel in Inner Mongolia Autonomous Region that integrates catering, accommodation, entertainment, and conferences. It has rooms, restaurants, bars, conference venues, theater shopping stores and national travel agency. Since its establishment, it has always been tasked with receiving party and state leaders, foreign heads of state, and important guests from all walks of life. In such large and important place, heating and sanitation water must be backed by boilers with excellent quality and safety in winter. After the bidding activities, Xincheng Hotel cooperated with ZOZEN boiler, and ZOZEN provided two sets of 6 tph WNS condensing gas-fired boilers. The thread smoke pipes of this series of boilers are high-efficiency heat transfer elements that ZOZEN boiler has been researching for many years. When satisfying the minimum flow resistance, the heat transfer coefficient is 1.2 times higher than that of ordinary tobacco pipes when the thread groove depth and pitch are selected.
Hot water inside a bagasse fired boiler described configuration (1) a substantial increase in the furnace inlet and outlet temperature, sound and light alarm overheating. (2) furnace and piping outgoing rhythmic percussion, pipe vibration. (3) furnace barometer hands shaking, the water pressure increases. (4) output vapor valves, Peng Zhang steam box. Followed by hot water boiler sake vaporized boiler water (1) a sudden termination of the pump power limit, a final break through the bad, or no effective countermeasure failure, leading to gasification. (2) furnace employees not yet Workout Do not use hot water boiler. Such as coal Stop, stop exhaust, induction stop, stop the pump mistakenly stopped, hot water boiler ignition, after the first ignition open; when shutdown, the pump stops after the first reduction furnace and so on. (3) due to not turn off the circuit through the bad incorrect valve entrance, gate or frozen cleaning conduit, dirt or the like clogging terminated. (4) hot water boiler or through a bad circuit leaks, invalid constant pressure equipment, not immediately moisturizing, resulting in water flow and pressure drop is not enough. (5) hot water boiler entrance thermometer, barometer ineffective, not processed in the furnace tube. (6) Zongtisheji scientific furnace, boiler or furnace into hot water by a steam boiler, a heating furnace so that flow rate is extremely well-balanced, part of the water heating surface due to slow gasification. (7) severe internal outfall stains or debris destroyed the water cycle. Hot water boiler pot of water vaporized solution: (1) rapid decrease lit, reduce the oven temperature. (2) when the limit power, back-up power to be coupled, or the reserved start of the circulation pump by the engine controller. (3) No back-up power and his response, the entrance and the return valve to be switched off, drinking water supply must furnace, and the furnace inlet and outlet drain valve to be open drain, the water can swim and furnace cooling heating surface, until the heat storage furnace has been cleared. When no drinking water or drinking water can not be sure that, decency backwater bypass pipe may be introduced to the furnace, then by a valve to exclude the cooling furnace heating surface. (D) Security Council notes furnace destruction, should replace them immediately. (5) When the furnace temperature increased significantly, gasification serious, should an emergency turn off the stove. About hot water boiler is vaporized sake and solutions.
