Description
Technical field
This utility model relates to heating system field, a kind of based on PID regulation and remotely control point
Cloth gas-heating system of hot water.
Background technology
For small scall coal-fired boiler, considerable coal-fired boiler has higher efficiency of utilization, and udst separation sets
Standby the most complete, manage relatively specification, from economy and environmental protection more preferably, and the small scall coal-fired boiler thermal efficiency is relatively low, udst separation
Facilities serialized is complete, Coal Stack Yard and coal cinder yard take up an area more, dispersion and pollute more serious, therefore, in natural gas shortage year in past
In generation, the cogeneration of heat and power with coal as fuel, central heating are the prevailing models of northern China various places development heating power supply, i.e. build
Concentrate burning coal boiler room for one, by pipe network, middle high-temperature-hot-water is sent to the heat exchange station of regional, then is changed by heat exchange station
The hot water of heat heating secondary pipe network, secondary network hot water is sent to terminal temperature difference, and a secondary net hot water then returns to concentrate boiler from heat exchange station
Room reheats.This pattern there is also cost height, one-time investment is big, difficulty of construction is high, pipe network heat loss big, Automated condtrol
The shortcomings such as degree is low, uneven in temperature, heat waste is big.
Economic development brings the increase of energy resource consumption, and environmental pollution is the severeest, and burning coal is atmosphere pollution
One of main source, the strict use limiting coal-burning boiler of country, improves the environmental emission standard of coal combustion equipment in recent years.?
In the case of haze weather is more and more serious, various places use natural gas clean energy resource to replace coal-burning boiler heating successively.But it is many
Coal changes combustion heating project and has still continued to use traditional coal-burning boiler central heating mode, and this heat-supplying mode is aobvious for natural gas heating
It is so out of season.
Natural gas is mainly composed of methane, nontoxic, easily distribute, and sulfur-bearing, dust and other harmful substances hardly, proportion is little
In air, damp should not be accumulated into, as a kind of clean energy resource, without sulfur dioxide and dust discharge amount, carbon dioxide
Only have coal fire discharged 60%, 50% with oxynitride discharge amount respectively, can fundamentally improve environmental quality.With coal-fired pot
Unlike stove, gas fuel is carried by pipeline, and calorific value is constant, no matter boiler capacity size, can realize height from
Dynamicization is run, and can obtain the highest operational efficiency, all have same environmental benefit.In natural gas, hydrogen atom quantity is many,
The water vapour of every cubic metre of combustion of natural gas generation reaches 1.5 kilograms, by flue gas condensing mode, flue-gas temperature is dropped to dew point
Below temperature, wherein part water vapour can be become water, discharge substantial amounts of gasification latent heat simultaneously, therefore natural gas boiler
Theoretical thermal efficiency, for low heat value, can reach 111%.And high-temperature-hot-water in traditional concentration pipeline for gas
Conveying, the backwater technological temperature that supplies of use is typically 115/70 DEG C or 130/70 DEG C, owing to return water temperature is higher than natural gas flue gas
Dew point temperature so that its water vapour heat be difficult to condensation reclaim, the thermal efficiency is difficult to break through 95%, the most no matter from cost, energy
Angularly, gas heating system needs to change according to the characteristic that gas fuel is exclusive for consumption or heating quality.
Additionally, the important step of heating and energy saving is that on the one hand operational management, extensive empirical formula management cause indoor super
The temperature waste energy, another aspect often occur that part building heating room temperature is the most up to standard, have impact on living of people, are controlling
Element quality is more and more reliable, control device is increasingly abundanter, in the case of information transmission more and more easily, by modern science and technology
Carrying out heat supply Automated condtrol accurately, heating quality will be made to be effectively ensured, heating energy consumption declines more than 30%, and heating is more
Energy-conservation, more environmentally friendly, and it is substantially reduced management work.
