vertical Biomass fired hot water boiler
Biogas and biomass are new emerging fuels for heat production in order to reduce carbon emission. These fuels frequently contain sulphur, which is converted into corrosive flue gas during combustion. The energy efficiency of biomass fired boilers or biogas fired boiler can be improved significantly via integration of waste heat from hot flue gas by heating combustion air or cold water.
How to deal with water shortage in electric steam boiler machine in use for some time this or that problem will be serious delays in the progress of work, causing great inconvenience to the people, such as water shortage, this problem arises in the use of electric steam boilers after a period of water shortage in how people deal with how to solve it. Electric steam boiler how to deal with water shortages: water level proofread each water level indicated by the right to judge whether the electric steam boiler water. In the electric boiler can not be determined when full of water or water vapor, can turn on the water faucet open water level, water flows out of the pot if not, indicating that water scarcity is an accident, otherwise it is full of water accidents. For the embodiment allows a small electric steam boiler waters operation, water may be called first, determines the electric steam boiler is mild or severe water shortage. This only applies to the water level gauge water hole communicating tube heating surface is higher than the highest water capacity and fire community large electric steam boiler. Otherwise it can not be called electric steam boiler water, because it will delay the time of the incident electric steam boiler water treatment, the worsening of the situation. When a slight electric steam boiler water, should reduce the fuel and air, the combustion decreased, and electric steam boiler feed water slowly to the normal level. Typically by adjusting a valve opening degree and the size, to control water flow rate and water, being careful not excess water. To quickly identify the cause of water shortage in the water and remove the process, and then check the electric steam boilers there is no unusual circumstances, after confirmation by the normal operation can resume electric steam boilers. When electric steam boilers severe water shortages, the need for emergency fire fighting shutdown. The fire shutdown procedures according to the method of implementation of the emergency shutdown, is strictly prohibited water to the pot and when serious water shortages. Some fireman personnel after the discovery of electric steam boiler water shortages, interrupted several times with water, each time a small amount of water replenishment way to cover up the accident electric steam boilers. This practice is very dangerous. If electric steam boilers are also less severe water shortage will cause biomass boiler leaks. If electric steam boiler water can cause serious electric steam boiler explosion. Only natural ventilation and cooling in electric steam boiler pot temperature dropped to below 70 ℃, water only slowly. Electric steam boiler for the water to normal level after thorough examination, no abnormal situation in order to re-start ignition, electric steam boilers to resume operation. Traditional old-fashioned coal-fired boiler using coal, gas, fuel oil and other fuel, these fuels are non-reusable primary energy, the future price will be higher. And the shortcomings of the traditional old-fashioned coal-fired heating methods are also caused by incomplete combustion, incomplete combustion can cause a lot of heat from the flue gas discharge out together, so it will cause energy losses. Boiler not only save electricity, but also saves time and effort, not the traditional coal-fired boiler heating boiler released by carbon dioxide, toxic gases, dust and other harmful substances, so users do not need to clean up, so it can save a large sum of maintenance cost.
Di steam boiler safety valve installation and adjustment of safety valves for steam boilers, its importance is self-evident, its purpose is to protect the safe operation of steam boilers, when the medium pressure steam boilers or pipes increases more than the prescribed the value is automatically turned on, the steam boiler safety shutdown. Biomass boiler is a kind of boiler to biomass energy as a boiler fuel called biomass boilers, steam boilers into biomass, biomass vertical biomass fired hot water boiler, biomass stove, biomass thermal oil heaters, vertical raw biomass boilers, biomass boilers and other horizontal. There are heating and hot water boiler bath for two purposes. Hot water boiler by circulating hot water circulation pump hot water holding tank, the tank hot water heating cycle can be achieved bath object; hot water boiler by circulating hot water circulation pump heating conduit, through the heat sink (radiator) people can achieve heating requirements; hot water boiler and hot water circulating pump with heat exchanger can be achieved bathing and heating dual function. Safety valve is so important, then for its installation, precautions, the author based on years of experience, in particular, are summarized below. 1. The safety valve safety valve should be installed after the installation of the boiler pressure test and adjust safety valve operating pressure at the first fire. The pressure should 7≤2 provided for in section 143 of the National Bureau of Labor Table "Supervision and Regulation steam boiler safety technology" to adjust. 2. Remove the adjustment valve opening pin, remove the cover, loosen the hex lock nut, the adjustment screw is then screwed, to relax or tighten the spring to meet the required pressure exhaust valve. After adjusting tighten the lock nut, and then install the remaining components. When the valve reaches a predetermined set pressure, it should be sealed lead-sealed, unless the check valve, otherwise not allowed to remove the lead seal at any other time. First, when adjusting the safety valve, the water level should be slightly lower than normal water level of the barrel, and ready to enter the water when the safety valve is opened. Second, do not knock any part of the safety valve, the safety valve can only be opened using the valve control lever. Finally, the boiler is absolutely prohibited until the safety valve is adjusted.
A few months ago, Shandong Provincial People's Government issued the "Opinions on Further expand domestic demand and promote development of up short board", which refers to: As of 2020, invested 11 million yuan to complete 5.4 million renovation to replace it clean, let 55 % of villages to achieve clean heating.
In the "clean warm winter Shandong Province Planning (2018-2022 years)" is mentioned, in 2020 the provincial average clean heating rate of 70%, of which more than 20 million people in the city basically clean heating full coverage. 2022, the province's clean heating rate of over 80%. Among them, more than the city and county basically clean heating full coverage, the average clean heating in rural areas reached about 75%.
Jinan, Qingdao, Yantai City 3 converts kinetic energy as a province of old and new core area, to take the lead in forming an electrical heating alternatives such as clean coal-fired heating San basic pattern. Should be in accordance with the electrical power, should be renewable energy sources of renewable energy, the principle of the dispersed phase concentration and binding, while the priority of central heating, the positive development of other energy sources for heating air.
