carbon waste heat boiler for food industry
In natural gas fuel for example, the high heat of about 9500kcal / m³, low heat generation of about 8600kcal / m³, a difference of about 900kcal / m³, 11% of low calorific value, choosing condensing carbon waste heat boiler for food industry compared to the conventional type boiler reduce operating costs of gas around 11%. (High and low calorific value science as detailed in another article)
To better implement the spirit of the CPC Central Committee nineteen Japanese National Assembly ecological and environmental protection, and resolutely respond Blue Sky Battle action, August 27, Qiqihar, Heilongjiang Province, the city government announced the "small coal-fired carbon waste heat boiler for food industrys Qiqihar City 2018-2020 to promote the phase-out plan" (the "program"), a more concrete of small coal-fired boilers on the basis of governance "Qiqihar City, 2018-2020 tough fight pollution prevention action plan" on.
"Plan" to improve air quality at the core, to take the most effective measures for key areas of work, the various departments collaborate together to complete the task of eliminating small coal-fired boilers.
"Plan" work plan is divided into three phases:
1, before the end of September 2018, in addition to the boiler must be retained, built-up areas in the central city and the rest of the county (city) to complete a full range of 10 steam tons / hour and coal-fired boiler or elimination process.
2, before the end of 2019, each county (city) out of more than 50% of the 10 steam tons / hour and coal-fired boilers.
3, before the end of 2020, in addition to the boiler must be retained, built-up areas outside the central city and the rest of the county (city) the scope eliminate or convert 10 tons of steam / hour and coal-fired boilers.
Boiler room can not be ignored security arrangement carbon waste heat boiler for food industry room layout: (1) general boiler should be installed in a special boiler room, rather than in densely populated rooms (such as bathrooms, classrooms, restaurants, audience room, conference rooms, waiting rooms, etc.) , or above or below, the sides of the main evacuation outlet; boiler. The room should not be near a crowded room. (2) when the boiler room is connected to the plant or production equipment, the boiler room must meet the requirements of "Boiler Safety Supervision" and "fire safety norms". (3) boiler room should have sufficient light and good ventilation, as well as the necessary cooling and freezing measures. Device is arranged to be easy to operate, and maintenance channel. (4) outside the boiler room door should be open during boiler operation, the door may not be locked or occupation; boiler room or living room doors should open the boiler room. Boiler room entrance should be accessible. (5) the operating site of the boiler room, and a water level meter, pressure gauges, thermometers, flow meters, etc., shall be provided with adequate lighting. Should spare boiler room lighting or tools.
What structure and principles of industrial carbon waste heat boiler for food industrys in particular? What structure and principles of industrial boilers in particular? Industrial boilers has become the hottest on the market boiler boiler. Whether it is gas or gas hot water boiler steam boilers, gas boilers generally use natural gas, liquefied petroleum gas and city gas as a fuel gas fuel. First, the working principle of gas steam boiler: the furnace and the combustion heat of the fuel gas steam boiler, heating pot of water evaporated into steam. Water pan (drum) in the furnace gases are fuel combustion energy released continuously heated, increasing the temperature and pressure steam is generated. When the boiling point of water increases with increased pressure, is sealed pot, the pot water vapor expansion is limited, and therefore the thermodynamic pressure (strictly speaking, water steam boiler). It is widely used as an energy source in the drum, the water is heated and vaporized again to saturation. Second, gas steam boiler basic structure: gas steam boilers and boiler drum consists of two body parts protection, instrumentation equipment, automatic control and protection system of continuous safe operation of its composition. This boiler water wall boiler drum boiler drum in the zoning arrangement, the first two return pipe fireworks smog chamber back to the drum. Connected between the drum and the tank, with water-cooling pipe and the downcomer, which constitute the framework of the combustion chamber. The pot is provided at the top with a steam water separator, to reduce the amount of water extracted from the steam. The bottom of the pan heating surface of the drum, and fireworks waterwall tubes.
